Question

calculate the virtual depth of a black dot at the bottom of a cubic block made of transparent glass with each side 4 cm while the refractive index of glass is 1.6​

Answer 1

Answer:

0.4

Explanation:

n=(real depth)/(Apparent depth)

1.6=4/a.d

a.d=1.6/4=0.4

hope it helps:-)

Answer 2

Answer:

n=1.6 ,real depth=4 , apparent depth = ?

n = (real depth)/(apparent depth)

1.6=4/apparent depth

apparent depth=4/1.6

apparent depth=2.5 Answer
