Transverse And Longitudinal Waves

Question 1

what do waves transfer and not transfer

Answer 1

• energy and information

- not matter

Question 2

what is the frequency of a wave

Answer 2

number of waves passing a point at a certain point

Question 3

what is the equation for the velocity of a wave using frequency

Answer 3

v = f * wavelength (lambda)

Question 4

what is a longitudinal wave

Answer 4

• a wave in which the particles vibrate left and right

- and are parallel to the direction of the wave

Question 5

what is a transverse wave

Answer 5

• a wave in which the particles vibrate up and down

- and are perpendicular to the direction of the wave

Question 6

example of a transverse wave

Answer 6

light

Question 7

example of a longitudinal wave

Answer 7

sound

Question 8

what is the formula for the velocity of a wave using time

Answer 8

v = x/t

Question 9

what is amplitude and what is it responsible for

Answer 9

• amplitude is the vertical length of a wave from the rest position (line drawn through the middle)
• `and is responsible for the distance an object travels to make noise

Question 10

what is the period of a wave

Answer 10

• the number of seconds it takes for one full cycle

- period = 1 / frequency

Question 11

how do longitudinal waves travel

Answer 11

• longitudinal waves squash up and stretch out the arrangement of particles in the medium they pass through
• making compressions and rarefactions
