Physics 2 Flashcards
(28 cards)
Frequency
How many wavelengths pass by in 1 second
Period
Time taken to complete one wavelength
Transverse wave
Particles vibrate perpendicular to the direction of the wave
Longitudinal wave
Particles vibrate parallel to the direction of the wave
Example of Transverse wave
EMR and Ocean Wave
Example of Longitudinal wave
Soundwave
Crest
Peak of the wave length
Trough
Bottom of the wavelength
Amplitude
Maximum displacement from the equilibrum position
Equilibrium position
The position of the particles if no disturbance travelled through the medium
Wavelength
Distance between successful identical parts of a wave
Refraction
Bending of light as it enters or exists medium
what are the two types of reflection
Specular reflection and diffuse reflection
Specular reflection
reflection from a mirror surface, where parallel rays all bounce off at the same angle
Diffuse reflection
the reflection of light from a surface where an incident ray is reflected at many angles
Snell’s Law
how light behaves when it travels from one medium to another
Natural frequency
the frequency at which a object naturally vibrates when disturbed
Forced vibration
when motion is sustained or driven by an applied periodic force
Resonance Forced Vibration
frequency of the forcing vibration matches the natural frequency of the object, resulting in a large amplitude of vibration
All waves
Carry energy from one place to another
Medium
material that allows waves to travel through it
Sound waves cant travel in
Vacuum
Sound transmit best/fast in what
Solids
Constructive interference
amplitude of waves gets doubled
