Question 1

Diffraction

Answer 1

Occurs when a wave encounters an obstacle or a small opening causing the wave to change direction and bend around the obstacle or spread through the opening. This results in a change in the wave’s direction and amplitude

Question 2

Wavelength of diffraction

Answer 2

Wavelength is the distance between 2 consecutive peaks or troughs of a wave. Shorter wavelengths result in more pronounced diffraction effects. The size and shape of the obstacle or opening affect the amount of diffraction that occurs

Question 3

What is diffraction essential for

Answer 3

Understanding the behavior of em waves like radio waves and micro waves AND understanding the behavior of particles like electrons as they interact with matter.

Question 4

Real life example of diffraction

Answer 4

Sound diffraction used in audio engineering to design concert halls and loudspeaker systems.

Question 5

A torch light rays spreads out after

Answer 5

Encountering an obstacle and bends around it. Obstacle tries to hold back the accelerating wave
