True or False? 20 questions
Question 1 Sound is a transverse wave
Question 2 The human ear can detect sound waves as low as 10Hz
Question 3 Amplitude is the maximum distance from the normal of a wave
Question 4 Frequency is the maximum disturbance in the wave.
Question 5 For a light ray reflected by a mirror, angle of incidence is greater than the angle of reflection.
Question 6 You cannot reflect all waves
Question 7 All waves are visible
Question 8 A virtual image can be projected onto a screen.
Question 9 If you see a tall, thin image of yourself, you are looking in a convex mirror.
Question 10 In sound the higher the frequency the higher the note
Question 11 A wave will travel faster in a less dense material
Question 12 A concave mirror always forms a real image
Question 14 In stars a red giant is hotter than a blue dwarf and has a higher frequency
Question 15 Waves can go around corners
Question 16 Digital waves have a range of frequencies
Question 17 Optical fibres use dispersion to transfer from one end to the other
Question 18 When sunlight passed through a raindrop it splits into a spectrum of colours. This is because light has different frequencies and wavelengths.
Question 19 A “ noisy” wave is a bad thing. Noise is interference but can be corrected.
Question 20 Write down as many uses of each type of wave as you can
