Vibrations involve a transformation of energy generally between ….?

A

Potential and kinetic

24
Q

Draw label transverse wave

A

S-shaped wave
LABEL: crest trough amplitude wavelength

25
Q

Draw label compression wave

A

Lots of circles/ coils
LABEL: compression rarefaction wavelength

26
Q

Sound moves —-?

A

Faster through : solids, liquids
Slower through : air/ gases

27
Q

Why is an echo softer than the original sound ?

A

When sound echoes, it travels a longer distance and reflects off surfaces, which causes it to lose energy and become softer than the original sound.
