The focal length of a spherical mirror will change depending on the water’s temperature. The mirror will have a shorter focal length at lower temperatures, and a longer focal length at higher temperatures.

## What will be the focal length of a concave lens whose power is 2.0 D?

A concave lens has a focal length of 2.0 D.

## Will there be any change in focal length of a convex lens is placed in water explain?

There is no change in focal length when a convex lens is placed in water.

## What happens to the focal length of a mirror when it is immersed in water?

When a mirror is immersed in water, the focal length of the mirror is shortened.

## How does a concave lens behave when immersed in a liquid having refractive index greater than the material of the lens?

A concave lens will have a higher index of refraction when immersed in a liquid with a higher refractive index than the material of the lens. This is because the liquid has a higher concentration of molecules that are able to scatter light in a particular direction.

## When a converging lens is immersed in water does its focal length increase or decrease in comparison with the value of its focal length in air briefly explain?

The focal length of a converging lens is not affected by the water droplets that it is immersed in. The focal length is affected by the lens’ design, which is based on its design principles.

## How do you find the focal length of a mirror?

There is no one definitive answer to this question. There are a few factors you can consider, including the size of your mirror, the type of mirror (square, round, or other), and the surface of the mirror.

## What is a lens Class 10?

A lens is a type of optical device used to focus light.

## How do you find the focal length?

There is no single answer to this question as it depends on the specific camera you are using and the focal length you are seeking. However, some tips on how to find the focal length of a camera can be found online or in a camera manual. One method is to use a focal length converter to find the correct focal length for your camera. Another way to find the focal length is to use a camera lens model number.

## WHAT IS lens formula?

The lens formula is the theoretical formula used to calculate the focal length of a lens.

## What happens to the focal length of a concave lens when it is immersed in water?

When a concave lens is immersed in water, the focal length decreases.

## When a spherical mirror is immersed in a liquid of refractive index?

When a spherical mirror is immersed in a liquid of refractive index, the mirror will reflect an image of the liquid at a different angle than when the mirror is not immersed.

## When an object is placed between F and 2F of a concave mirror would the image formed be?

No, the image would not be formed because the object is greater than the mirror’s surface area.

## What is effect on the focal length of the convex mirror when it is immersed in a liquid of greater refractive index *?

The focal length of a convex mirror is increased when it is immersed in a liquid of greater refractive index. This is because the liquid has a greater surface area for reflecting light and the mirror’s surface is also curved.

## What happens to their focal lengths when they are immersed in a medium of refractive index higher than that of air?

The focal lengths of a lens are increased when it is immersed in a medium with a higher refractive index than air. This is because the lens is a two-dimensional object and the distance between the lens and the object is increased.

## Is immersed in water μ 4 3 The focal length of the mirror in water will be?

Yes, the focal length of the mirror in water will be the same as the focal length of the mirror in air.

## How the focal length of a mirror change when it is placed in water 1 point it will increase it will decrease no change it will decrease half?

When a mirror is placed in water, the focal length will change depending on the angle of incidence. The following equation will be used to calculate the focal length of a mirror in water: focal length = (angle of incidence) / (angle of reflection)

## How is focal length related to refractive index?

There is no one answer to this question as it is a complex topic. However, one way to think about it is that focal length is related to the size of the lens aperture. The smaller the aperture, the smaller the lens will be able to focus on a target. Focal length also affects the magnification of a lens. A larger aperture will allow a lens to magnify things a greater amount, which can be helpful for photography or video.

## What is mirror formula?

The mirror formula is a set of instructions for manufacturing a mirror.

## What will be the change in focal length f of a concave mirror when immersed in a liquid of refractive index n?

When a concave mirror is immersed in a liquid of refractive index n, the focal length will change according to the inverse of the square of the liquid’s index. The focal length will be smaller when the liquid is near the mirror’s surface and will be larger when it is far away.

## What happens when a convex lens of refractive index 1.5 is immersed?

The lens will change its shape, becoming more convex.

## Does focal length change in water?

There is no definitive answer to this question as different factors, such as light and water temperature, can affect the focal length of a lens. However, some experts believe that focal length can change in water, depending on the angle of incidence and the water’s surface roughness.

## What happens when convex lens is immersed in water?

When a convex lens is immersed in water, it will distort the image.

## What is the focal length of a convex mirror?

A focal length is the distance between the mirror’s surface and the object it is reflecting.

## When a concave lens of refractive index 1.5 is immersed in water it will become?

When a concave lens of refractive index 1.5 is immersed in water it will become a water droplet.

## When concave lens of glass is immersed in water it works as?

The concave lens of glass works as a water droplet lens because it gathers water droplets that are smaller than the diameter of the lens. When the lens is immersed in water, the smaller droplets fall on the surface of the lens and are collected by the lens.

## Why does the focal length increases in water?

The focal length increases in water because the water’s surface tension is greater than the air’s tension. This means that when light waves hit the water, they are scattered more than when they hit the air. This causes the focal length of a lens to increase as the lens gets closer to the water’s surface.

## How do you find the focal length of a mirror in water?

There is no definitive answer to this question as the focal length of a mirror in water can vary depending on the water’s temperature, clarity, and other factors. However, a general rule of thumb is that a mirror’s focal length is about twice the size of its diameter.

## What is the formula of lens and mirror?

The formula of a lens and mirror is a three-dimensional equation that describes how the light from a source is reflected off of a surface.
