Question

1) state the law of refraction of light with two examples for refraction of light in daily life
2) a convex lens of focal length is 10 cm calculate its power?​

Answer 1

Answer:

1.Its the appearance of a distant object or objects caused by the bending of light rays (refraction) in layers of air of varying density. See in the picture. In camera lens refracts light and projects an opposite image. The same thing also happens in our eyes.

2. The power of the convex lens is 10D

Answer 2

$\huge\red{\underline{✪Answer}}$

1) Its the appearance of a distant object or objects caused by the bending of light rays (refraction) in layers of air of varying density. In camera lens refracts light and projects an opposite image. The same thing also happens in our eyes.

2) $f = 10cm = 0.1m$

$Therefore$

$\frac{p = 1}{f}$

$\frac= {1}{0.1}$

$= 10 D$
