What is a transverse wave?
A wave in which the vibrating source moves perpendicular to the point of propagation in the wave.
What is a trough?
Minimum displacement below the rest point
What is a crest?
Maximum displacement above the rest point
What is max plank’s constant ?

What is frequency?
Frequency is the number of waves passing a point in a second
What is period?
Period is the amount of time it takes for a wave to pass a point
What is velocity?
The distance travelled by a wave per unit of time(m.s^-1) basically speed?
What is a longitudinal wave?
Displacement of particles in the medium is parallel to the direction of propagation of the wave
Compression?
Area of high pressure
Refraction
Area of low frequency
What is elasticity?
It is the characteristic of a material to keep its for, and not chamber when it gets subdued by a force
High frequency =?

Low frequency?
Low pitch
