Answer 2

Answer:

The materials required to find the focal length of the concave mirror are a concave mirror, a measuring scale, screen support, a mirror stand and a mirror holder. The procedure is that the selected different objects should be at least 50 feet apart and the concave mirror should be facing the faraway item when it is set up on the mirror stand. The mirror's reflecting surface should be in front of the screen. The distance between the concave mirror and the screen is equal to the concave mirror's stated focal length.

Explanation:

1. The materials required to find the focal length of the concave mirror are:

A concave mirror,

A measuring scale,

a screen support

a mirror stand

a mirror holder

2. The procedure to  find the focal length of a concave mirror is as follows:

• The selected different objects should be at least 50 feet apart.
• The concave mirror should be facing the faraway item when it is set up on the mirror stand.
• The mirror's reflecting surface should be in front of the screen. The screen should be adjusted in order to have a sharp, clear image.
• The distance between the concave mirror and the screen can be measured using a metre scale. The distance is equal to the concave mirror's stated focal length.
• Refer to the below-given observation table and experimental setup to find the focal length of a concave mirror.

Thus, The materials required to find the focal length of the concave mirror are a concave mirror, a measuring scale, screen support, a mirror stand and a mirror holder. The procedure is that the selected different objects should be at least 50 feet apart and the concave mirror should be facing the faraway item when it is set up on the mirror stand. The mirror's reflecting surface should be in front of the screen. The distance between the concave mirror and the screen is equal to the concave mirror's stated focal length.
