Q1
A parallel beam of light of wavelength 500 nm falls on a narrow slit and the resulting diffraction pattern is observed on a screen 1 m away. It is observed that the first imum is at a distance of 2.5 mm from the centre of the screen. Find the width of the slit.
Q2
Answer the following questions:
(a) When a low flying aircraft passes overhead, we sometimes notice a slight shaking of the picture on our TV screen. Suggest a possible explanation.
(b) As you have learnt in the text, the principle of linear superposition of wave displacement is basic to understanding intensity distributions in diffraction and interference patterns. What is the justification of this principle?
Q3
In deriving the single slit diffraction pattern, it was stated that the intensity is zero at angles of n/a. Justify this by suitably dividing the slit to bring out the cancellation.

Verified
(a) Weak radar signals sent by a low flying aircraft can interfere with the TV signals received by the antenna. As a result, TV signals may get distorted. Hence, when a low flying aircraft passes overhead, we sometimes notice a slight shaking of the picture on our TV screen.
(b) The principle of linear superposition of wave displacement is essential to our understanding of intensity distributions and interference patterns. This is because superposition follows from the linear character of a differential equation that governs wave motion. If are the solutions of the second-order wave equation, then any linear combination of will also be the solution of the wave equation.
