# Topics 2.1 and 2.4 - General Properties of Waves and Reflection

?
What can waves transfer?
Waves can transfer energy and information without transferring matter
1 of 13
What happens in a transverse wave?
In a transverse wave the oscillations are perpendicular to the direction of energy transfer
2 of 13
What happens in a longitudinal wave?
In a longitudinal wave the oscillations are parallel to the direction of energy transfer
3 of 13
What waves are Transverse?
Electromagnetic waves are transverse
4 of 13
What waves are longitudinal?
Sound waves are longitudinal?
5 of 13
What waves can be both transverse and longitudinal?
Mechanical waves
6 of 13
What can waves be?
Waves can be reflected, refracted or diffracted
7 of 13
What happens when identical waves overlap?
They interfere with one another
8 of 13
How can waves be described?
In terms of their frequency, wavelength, time period and amplitude
9 of 13
What is the relationship between wave speed, frequency and wavelength?
Wave Speed = Frequency x Wavelength
10 of 13
What happens when waves are reflected?
The angle of incidence is equal to the angle of reflection
11 of 13
What is the normal?
The normal is a construction line perpendicular to the reflecting surface at the point of incidence
