Answer 2

Answer:

the distance of the image of the sun from the water surface at noon is 13.33 cm.

Explanation:

A concave mirror is a type of curved mirror that bulges inward. It forms an inverted image of the object placed in front of it. The distance at which the mirror focuses incoming light is called the focal length.

In this problem, we have a concave mirror with a focal length of 50 cm and it is placed at the bottom of a water-filled bucket with a depth of 40 cm. When the sun is shining at noon, its rays reach the water surface, and as they pass through the water and reach the concave mirror, they get reflected and form an image. The location of this image can be calculated using the mirror equation.

The mirror equation is given by:

1/f = 1/d + 1/d'

Where,

f = focal length of the mirror (50 cm)

d = distance of the object from the mirror (40 cm)

d' = distance of the image from the mirror

Solving for d', we get:

d' = (f * d) / (f + d) = (50 * 40) / (50 + 40) = 13.33 cm.

So, the distance of the image of the sun from the water surface at noon is 13.33 cm.
