P1.5.5 Wave Properties - Diffraction 0.0 / 5 ? PhysicsWavesGCSEAQA Created by: MaddiCreated on: 30-04-14 15:14 What do we mean by diffraction? Diffraction is the spreading out of waves when they pass through a gap or around an obstacle. 1 of 5 What is the effect of gap width on the diffraction of waves? The narrower a gap is, the greater the diffraction is. 2 of 5 Why is radio and TV reception often poor in hilly areas? If radio waves do not diffract enough when they go over hills, radio and TV reception will be poor. 3 of 5 Why don't we often observe diffraction of light during everyday life? Because the wavelength of light is very short. 4 of 5 What sort of waves are diffracted? All waves are diffracted. 5 of 5
