Physics revision Flashcards
Define wave.
A wave transfers energy without transferring matter
In which type of wave does the energy move at right angles to the particle movement?
transverse waves
Give one example of a longitudinal wave.
sound
What is the formula when solving the frequency of a wave?
F = V/λ
What is the formula when solving the wavelength of a wave?
λ = V/F
What is the formula when solving the velocity of a wave?
V = F x λ
Explain how a triangle makes a sound when struck.
- When hitting the triangle, the air particles next to it vibrate.
- The particles are getting further apart.
- The sound energy is transferred as these particles cause the particles next to them to vibrate.
- hence the ear can hear the sound.
Write conclusions on what will determine loudness and pitch of the sound.
The larger the amplitude, the louder the sound
The higher the frequency (the shorter the wavelength), the higher the pitch
What wave does light travel in?
Transverse
What does light travel as?
An electromagnetic wave
Does light require medium to travel through?
It does not require medium, so it can travel through a vacuum
Light travels in straight lines
true or false?
true
Different _________ of light are observed as different colors.
Spectrum
What light is made of all colours combined?
White light
A prism splits white light in a process called…
Dispersion
