(693-909 kHz)
Question 6
You cannot reflect all waves
Question 7
All waves are visible
Question 8
Diffraction is where waves change direction due to a change in speed
Question 9
A Tsunami is made of lots of little waves creating one big wave as in interference
of waves
Question 10
In sound the higher the frequency the higher the note
Question 11
A wave will travel faster in a more dense material
Question 12

Question 15
Waves can go around corners
Question 16
Digital signals 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 sunlight is made up of different
frequencies and wavelengths.
Question 19
A “ noisy” wave is a bad thing. Noise is interference but can be corrected.
Question 20
