what is a wave?

• any disturbance that transmits energy from one place to another

• travels with air

• a requirement to transmit energy

• energy is carried

medium

• both of these

• a substance or material that carries the wave

• water,ground,rope are mediums

• none of these

two types of waves

• sound

• mechanical

• transverse

• longitude

transverse wave

• electromagnetic light waves is an example

• crest and trough

• all of these

• particles vibrate up and down

longitude wave

• particles vibrate back and forth

• pushing a string back and forth is an example

• compression and rarefaction

• sound waves is an example

properties of a wave

• all of these

• amplitude

• wavelength

• frequency

amplitude

• none of these

• distance between the line through the middle of the wave and a crest or trough

• the bigger the amplitude the more energy

• both of these

wavelength

• both of these

• one of these

• distance from one wave crest to the very next

• measure from trough to trough

frequency

• both of these

• one of these

• number of waves passing a point at a time

• count the number of crests that pass the point in one second

what is sound?

• known as mechanical waves

• longitude wave

• all of these

• a wave produced by vibrating object
