Wave What is a disturbance that transfers energy?

What is any substance a waves moves through? Such as Air, water, and soil Medium

What is bending of a wave as it passes into a new medium at an angle other than 90 degrees. Refraction

What type energy is transferred when a rock is dropped into a pond to create waves? Kinetic energy

What type waves require a medium? –Soil, water, and air Mechanical Waves

Identify each type wave? A- Transverse wave B- Longitudinal wave

What is the distance from the center of one compression to another? Wave length

What is points A and B on the longitudinal wave called? A- compression B- Rarefaction

What is the distance a medium travels above or below its position at rest? Amplitude

What type waves transfer energy through matter? Mechanical Waves

What is the frequency of the wave expressed in wavelengths per second? 1/8 s =

What is the distance a medium travels above or below its position at rest? Amplitude

What is the area marked “A” on the longitudinal wave called? Wavelength

What is the term that describes when two waves join to form a bigger wave? Constructive Interference

What is the frequency of the wave expressed in wavelengths per second? 2/10 s =

What is the term called when light waves bounce off a mirror? Reflection

Identify the type wave shown below Transverse wave

What is the highest point on the wave labeled “A’ called? Crest

What is it called when ocean waves bump into an island and bend around it? Diffraction

What is the lowest part of the waved marked “A” called? Trough (trawf)

What is the number of wavelengths passing a fix point in a certain amount of time Wavelength

How many wavelengths are present on the longitudinal wave? Two wavelengths

What is it called when bats send out sound waves (chirp or squeal to locate food? Echolocation
