waves test science

waves

A disturbance that moves energy from one place to another

medium

any type of matter that is disturbed by energy

Crest

the highest point of a wave

trough

the lowest point of a wave

Wave length

the distance between the middle of two crests or two troughs

Two major types of waves

mechanical and electro magnetic waves

Two types of mechanical waves

ocean waves and sound waves

amplitude

the measurement of how much energy a wave is carrying

amplitude of sound waves

Volume

frequency

the number of waves that pass a point in one second

frequency of sound waves

Pitch

Electromagnetic wave

Waves that don’t need a medium to travel through

Electromagnetic wave examples

Light waves, radio waves, x ray waves, up ray waves, micro waves

Mechanical wave

Waves that need a medium to travel through

Two types of mechanical waves

Longitudinal and transverse waves
