Longitudinal and transverse waves

what happens when waves reach a boundary between two different mediums

they are either, reflected, absorbed or transmitted

waves transfer _______ from one place to another

energy

What is the time period of a wave?

The time taken for one complete oscillation

Equation for frequency

f = 1/T

T = time period

equation for wave speed

wave speed = frequency x wavelength

What is the amplitude of a wave?

the distance between the middle and crest or trough of a wave

What is the crest of a wave?

the highest part of a wave

What is the trough of a wave?

the lowest part of a wave

what is the displacement of a wave?

How far a point on the wave has moved from its undisturbed position( from the x-axis middle line)

what is one entire oscillation of a wave

from one crest to another

transverse wave

oscillations are perpendicular to the direction of energy transfer

examples of transverse waves

electromagnetic

radio waves

ripples/waves

longitudinal wave

Oscillations are parallel to the direction of energy transfer

Examples of longitudinal waves

Sound, Seismic P-waves
