Waves

Question 1

How are Radio Waves produced

Answer 1

Electrons moving through an antenna are resisted and cause electromagnetic waves to radiated outwards.

Question 2

what is Velocity

Answer 2

Speed of the wave (Direction and magnitude)

Question 3

Frequency

Answer 3

The number of waves that pass a fixed point in one second

Question 4

Wavelength

Answer 4

Distance between two waves measured from the same points.

Question 5

Period

Answer 5

The time to complete one cycle (two waves measured at the same point)

Question 6

Amplitude

Answer 6

The maximum movement positive and negative to the mean

Question 7

Longitudinal wave

Answer 7

The wave moves in the same direction as propogation Compression and refraction (Sound)

Question 8

Longitudinal wave

Answer 8

Particles of the medium move perpendicular to the direction of propagation. (waves on water)
