Answer:
R= 1.6 m
Explanation:
The radius of curvature of mirror and focal length is given by
R=2f
where R is the radius of curvature
f is the focal length
As the telephoto camera uses mirror instead of lens , we can calculate the radius of curvature of mirror which has focal length of 0.8m which is same as that of lens.
The radius of curvature of mirror is R =2*0.8
R= 1.6 m
