Question

write an experimental method in measure the distances of object and image using concave mirror and write the table for observations.​

Answer 1

$SolutiOn :-$

To determine focal length of a given concave mirror  

Materials Required  :-

• A concave mirror

• A measuring scale  

• A screen holder

• A mirror holder

• A mirror stand

• Procedure

The distance between the selected distinct object should be more than 50 ft.

The concave mirror placed on the mirror stand and the distant object should be facing each other.  

The screen should be placed in front of the reflecting surface of the mirror. To obtain a clear, sharp image the screen should be adjusted.

Using a metre scale the distance between the concave mirror and screen can be determined. The distance is the same as the focal length of the given concave mirror.

Repeat the above procedure thrice to calculate the average focal length.

Answer 2

Answer:

solution :-

to determine focal length of given concave mirror

material Required :-

. CONCAVE MIRROR

. A MASERRING SCALE

. A MIRROR HOLDER

. A MIRROR STAND

. PROCEDURE

THE DISTANCE BETWEEN THE SELECTED DETINCT OBJECT SHOULD BE MORE THAN 50 FT

THE CONCAVE MIRROR PLACED ON THE MIRROR STAND AND THE DISTANT OBJECT SHOULD BE FACING EACH OTHER

THE SCREEN SHOULD BE PLACED IN FRONT OF THE REFLECTING SURFACE OF THE MIRROR. TO A CLEAR, SHARP IMAGE THE SCREEN SHOULD BE ADJUSTED.

UASING A MATRE SCALE THIS DISTANCE BETWEEN THE CONCAVE MIRROR AND SCREEN CAN BE DETERMINED. THE DISTANCE IS THE SAME AS FOCAL LENGTH OF THE given concave mirror.

REPEAT THE ABOVE PROCEDURE THRICE TO CALCULATE THE AVERAGE FOCAL LENGTH.
