Properties Of Waves EOY9

Question 1

What do waves transfere

Answer 1

Energy and information

Question 2

How are waves formed?

Answer 2

Waves are formed by an oscillation or disturbance of a medium, or substance.

Question 3

What are the w types of waves?

Answer 3

Transverse and longitudinal

Question 4

Describe a longitudinal wave and give an example.

Answer 4

With longitudinal waves, the direction of particle oscillation is parallel to the direction or travel of the wave energy. Example sound

Question 5

Describe a transverse wave and give and example.

Answer 5

With transverse waves, the direction of particle oscillation is perpendicular to the direction of travel of the wave energy. For example light, water wave

Question 6

What is amplitude?

Answer 6

Amplitude is the distance to the peak from the waves midpoint (measured in m)

Question 7

What is the wave length?

Answer 7

Wavelength is the distance between two consecutive peaks or troughs (measured in m)

Question 8

What is the time period?

Answer 8

Time period is the time take for one oscillation of a wave (measured in s)

Question 9

What is frequency?

Answer 9

Frequency is the number of complete waves per second (measured in hertz hz)

Question 10

What does frequency equal?

Answer 10

Frequency Hz = 1/time period (s)

Question 11

What is the equation for wave speed?

Answer 11

Wave speed = frequency x wavelength
