Use letter choices below for both parts
Part (a) Which of the following phenomena is exploited to make the lends in a camera work?
Part (b) Which of the following phenomena causes the lens in a camera to work less than perfect (e.g. blurred image)?
A. Refraction
B. Differaction
C. Reflection
D. Dispersion
E. Total internal reflection
Homework Answers
Part (a): A photographic camera works on the principle of refraction of light. The light refracted when passing through the lens and formed a photograph. Answer: (A) Refraction
Part (b): When Diffraction takes place it causes the lens in a camera to work less than perfect (e.g. blurred image). That means due to diffraction a photograph grows progressively less sharp. Answer: (B) Diffraction.
