Question

Question 4 (1 point) A person is using a makeup/shaving mirror with their nose 8.0 cm from the concave spherical surface of the mirror, which has a radius of 32 cm. The distance from the mirror to the image of the person's nose is: 12 cm 24 cm 16 cm 32 cm 8.0 cm

Answer 1

For concave lens $f= \frac{R}{2}$

We know lens equation

+

given:

u= - 8 cm

f= -32/2= -16 cm

So,

$-\frac{1}{8}+\frac{1}{v}= -\frac{1}{16}$

Thus , v= 16 cm

Ans: 16 cm
