Question

A concave spherical mirror has a radius of curvature of 11.0 cm.

a) The location of the image formed by an 10.0-mm-tall object whose distance from the mirror is 22.0 cm is 7.33 cm.Calculate the size

b) The location of the image formed by an 10.0-mm-tall object whose distance from the mirror is 11.0cm .is 11.0 cm. Calculate the size.

c)The location of the image formed by an 10.0-mm-tall object whose distance from the mirror is 2.75 cm. is -5.50 cm. Calculate the size.

d)Calculate the location of the image formed by an 10.0-mm-tall object whose distance from the mirror is 10.0 cm. Also Calculate the size.

All answers in mm

Explanation / Answer

B) 1/f=1/u+1/v =1/11+1/11 f=5.5cm magnification factor=-(V/U)=-(11/11)=-1 size of image=size of object*magnification factor=10*-1=-10mm(negative sign indicates it is inverted)
