Use Of Waves Flashcards
What are transverse waves?
Oscillations are perpendicular transverse waves which move up and down
What are longitudinal waves
The oscillations are parallel where rarefractions and compressions occur
What’s amplitude?
Amplitude is the height of the wave
What’s the wave speed equation?
Speed= Frequency X wavelength
Where does Diffraction Occur?
Diffraction Occurs when a wave passes through a narrow opening
What happens when the reflection of light at its interface?
Light crosses direction when it crosses in interface
Where can Diffraction can be seen
It can be seen in colours on a Dvd
