Question

Which of the followings lens will diverge the ray of light more
(a) 2 D
(b) 1D
(c) -0.4 D
(d) -0.8 D​

Answer 1

Answer:

Option d - 0.8D is the correct answer

Explanation:

Concave lens diverges the ray of light and their magnification power is always negative. So, option D is the correct answer

Hope it helps you ☺️

Answer 2

-0.8 D will max diverge the light ray .

• First of all, we know that concave lens are diverging lens. This is because, light rays falling on the concave lens undergo refraction and go away from each other.

• Again, we know that : Power is defined as the converging or diverging power of any lens. Higher the power, higher will be the deviation.

• From the options, we need a high power concave lens.

$\star$ So, -0.8 D is the highest power CONCAVE LENS from the options.
