waves

Question 1

what is a transverse wave

Answer 1

are waves where the direction of the particles is perpendicular to the direction in which the wave travels .

Question 2

examples of Transverse waves

Answer 2

Electromagnetic waves
Secondary seismic waves
Waves on a string/ wire
Ripples on water

Question 3

what is a longitudinal wave

Answer 3

are waves where the direction of vibration of the particles in the wave is parallel to the direction in which the wave travels.

Question 4

examples of longitudinal waves

Answer 4

Sound waves
Ultrasound waves
Primary seismic waves (P-waves)

Question 5

Longitudinal waves show areas of compression and rarefaction. what are these

Answer 5

Compression - where the particles are close together
Rarefaction - where particles are far apart

Question 6

what is oscillation

Answer 6

regularly repeating motion about a central value (equilibrium position )

Question 7

what is Displacement

Answer 7

of a vibrating particles is it distance and direction from its equilibrium position

Question 8

what is amplitude

Answer 8

of a wave is the maximum displacement of a vibrating particle. In a transverse wave this is the vertical distance from equilibrium to either a crest (top) or a through (bottom)

Question 9

what is Wavelength

Answer 9

is the length of one whole cycle. It can be measured between two adjacent peaks, troughs or any point on a wave and the same point one wave later

Question 10

what is One complete cycle

Answer 10

is from maximum displacement to the next maximum displacement (e.g form one wave peak to the next )

Question 11

what is period

Answer 11

is the time for one complete wave to pass a fixed point

Question 12

what is frequency

Answer 12

is the number of cycles of vibrations of a particle per second, or number of complete waves passing a point per second

Question 13

wave speed equation

Answer 13

v=fλ
Where:
v= wave speed(m/s)
f= frequency (Hz)
λ=wavelength (m)

Question 14

What are waves

Answer 14

A wave is a way of transferring energy (and momentum) from one point to another without there being any transfer of matter between two points
