Mod 3: Lecture 1 - Wave Characteristics Flashcards
1
Q
How do waves travel in transverse waves?
A
The particles of the medium oscillate perpendicular to the direction of energy propagation.
2
Q
What speed do EM waves travel at?
A
Constant speed of 3x10^8ms^-1 in a vacuum or in air.
3
Q
What is frequency in relation to waves?
A
The number of complete oscillation in one second.
4
Q
What is a period in relation to waves?
A
The time taken for a particle to make one complete oscillation. Where T=1/f
5
Q
State the formula for velocity of a wave that will travel in one wavelength
A
v=f x landa
