what is a tranverse waves | A transverse wave vibrating at a right angle (transversely) to the spring |
What is longitudinal waves | It is when the vibrating (or oscillating) it is vibrating lengthways or longitudinally |
what are the high parts called | crests |
What are the low parts called | Troughs |
what is the amplitude of a wave | It is the hight of a crest above the average water level or the depth of a trough below it |
What is the wavelength | It is the distance between two crests or trough |
What is the frequency | It is how many complete waves every second |
If the vibrations of a wave are at right angles to the directions of the wave it is called ..... | Transverse waves |
if the vibration of the wave along the direction of the wave it is called a ..... | Longitudinal wave |
A water wave is a ... | Transverse wave |
A sound wave is .... | Longitudinal wave |
The wavelength of a wave is the distance between two successive...... | Crests or trough |
The frequency of a vibration is measured in .... | Hz it is the number of complete Wave per a second |
When a ray of light is reflected from a shiny surface ( e.g a plane mirror ) the angle of incident is equal to ..... | The angle of reflection |
What do we use waves for | Waves are vibrations that transfer energy from place to place |
What are the vibrations of a transverse waves | With a transverse wave the oscillation ( vibration ) of the particles is perpendicular to the direction in which the wave travels |
