waves

Question 1

longitudinal and transverse waves

Answer 1

• transverse waves- the oscillations are perpendicular to the direction of the energy transfer (shown as a squiggly line in a diagram)
• longitudinal- the oscillations are parallel to the directions of the energy transfer

Question 2

frequency meaning

Answer 2

number of waves passing a fixed point per second, measured in hertz (Hz)

Question 3

amplitude meaning

Answer 3

maximum displacement that any particle achieves from its undisturbed position in metres (m)

Question 4

wavelength meaning

Answer 4

distance from one point on a wave to the equivalent point on the next waves in metres (m)

Question 5

period meaning

Answer 5

time taken for one complete oscillation in seconds (s)

Question 6

the more energy, the higher the ______

Answer 6

amplitude

Question 7

equation for working out period

Answer 7

1
———-
frequency

t=1 divided by f

Question 8

what is wave speed

Answer 8

speed of a wave is the speed at which the energy is transferred (or the way the wave moves)

Question 9

equation for wave speed

Answer 9

frequency x wavelength
