EOUT3 B

Question 1

59: define amplitude

Answer 1

amplitude is the maximum particle displacement from the equilibrium

Question 2

59: define frequency

Answer 2

frequency is the number of oscillations per unit time

Question 3

59: define time period

Answer 3

time period is the time taken for one complete oscillation

Question 4

59: define wave speed

Answer 4

wave speed is the distance travelled by the wave per unit time

Question 5

59: define wavelength

Answer 5

wavelength is the minimum distance between two points in phase, crest to crest/trough to trough

Question 6

60: equation for wave speed

Answer 6

wave speed = frequency * wavelength

Question 7

61: define longitudinal waves

Answer 7

In a longitudinal waves, the particles oscillate parallel to the direction of propagation of the wave
Consists of rarefactions (low pressure regions), and compressions (high pressure regions)

Question 8

62: define transverse waves

Answer 8

In a transverse wave, the particles oscillate perpendicular to the direction of the wave.
Consists of peaks (maximum positive displacement) and troughs (maximum negative displacement).
