Question

a concave mirror used in a bus radius of curvature 3.5 m if the driver of the bus locate agar at 10.0 m behind the bus find the position nature and size of the image car

Answer 1

Answer:

R=3.5 , f=R/2= 1.75m

u= -10cm, v=?

1/f =1/v + 1/u

1/1.75 = 1/v - 1/10

v= 1.5 m

magnification (m)= -v/u =0.15

image is real, erect and diminished
