Reflection, Refraction and Sound
Karten in diesem Stapel (8)
- 1The normal can be found where?at a 90º angle from where the ray meets the boundary
- 2refractive indexthey way in which the material affects refraction
- 3Refraction is due to what?the difference in wave speed in the different media
- 4Why is the angle of refraction different to the angle of incidence?The first part of the wave that enters the medium changes speed, but the rest of the wave is at the original speed causing the wave to change direction either away from the normal if it speeds up, or towards the normal, if it slows down.
- 5The amplitude of a sound wave relates to itsvolume
- 6The frequency and wavelength relate to itspitch
- 7The normal range of human hearing is20Hz to 20kHz(20,000Hz)
- 83 examples of sound waves being converted to vibrationear drum, microphone and glass being shattered by an opera singer
