Waves Flashcards
(16 cards)
What are waves made up of?
Vibrations being passed on from particle to particle
What is the symbol for wavelength?
Lamda (upside own y)
What is amplitude?
The size of a maximum displacement
What is a wavelength?
The distance between two corresponding points on the wave
Measured in metres (m)
What is frequency?
How many waves pass by every second
Measured in hertz (Hz)
Frequency equation:
1/Time
Velocity equation:
Wavelength/time
Wave equation:
Wavelength x frequency
What is the speed of sound?
330m/s
How are wavelengths generated?
By accelerating/decelerating/ vibrating any charged particles
What is the speed of light?
3 x 10^8 m/s
Angle of incidence =?
Angle of reflection
Glass is more sense so does what to the wave length?
Decreases it
Through glass, light bends…?
Towards the normal
What is refraction?
When waves speed up/slow down due to travelling in a different medium
What is the critical angle?
42 degrees
