IB Physics Topic 3 Definitions
It is the maximum displacement of the particle from its mean position
It is a polarizer that detects the angle of polarization
It is the angle oscillated per unit time
It is a point a maximum amplitude in a standing wave
It is the increase in frequency of light due to the moving closer of an observer or source
These are the conditions that must be present at the edges of a system for a standing wave to be formed. Also called resonant modes
It is the interference of in phase waves leading to a summation into a larger amplitude wave
It is the interference of out of phase waves leading to a summation into a zero amplitude wave
It is an area of high particle density in a longitudinal wave
It is interference that increases the displacement of both waves
It is the angle at which there is no refraction and complete reflection back into the medium
It is interference that decreases the displacement of both waves
It is the spreading of waves after passing through apertures, resulting in an energy distribution in the geometric shadow region
It is the reflection of several rays from a rough surface
It is the net distance an object has travelled from its starting point in a direction
It is a transverse wave with an electrical and magnetic component
It is the resonant mode with the lowest frequency
It is the number of oscillations in one second
It is the pattern of light and dark regions formed by diffraction
It is the region not in line with the aperture
These are waves with a phase difference of zero or path difference of nλ
It is the energy per unit area
It is the superposition of two waves of the same type when they come together
It is a travelling wave where the oscillation is parallel to the direction of energy transfer
It is a source that emits one frequency of light
It is a point at rest in a standing wave
They are the continual movement of an object around a fixed point, creating a cyclical path the object travels to constantly interchange between kinetic and potential energy
These are waves with a phase difference of 180° or path difference of (n+1/2)λ
It is the reflection of a single ray from a smooth surface
It is the time it takes to complete one oscillation
It is the measure of the alignment of two oscillations
It is the plane of the electric field of an electromagnetic wave and the direction of wave propagation
It is light with a fixed plane of vibration
It is a device that transforms unpolarized light into plane-polarized light
It is an area of low particle density in a longitudinal wave
It represents the direction of travel of wave energy
It is the decrease in frequency of light due to the moving away of an observer or source
It is the scattering of a wave when it hits a surface
It is the change in direction of a wave when it crosses from one medium to another due to a change in wave speed
It is the motion of an object where its acceleration is proportional to and towards its displacement
It is the spreading of a wave through a single aperture
It is a wave whose spatial pattern remains constant whilst the amplitude changes
It is the complete reflection of a wave back into the medium
It is a travelling wave where the oscillation is perpendicular to the direction of energy transfer
It is an oscillating wave that transfers energy through a medium via the movement of particles in the direction of the wave at a constant speed
It is light with a randomly varying plane of vibration
It is a non-sinusoidal disturbance of a medium that propagates as a half of a wave
It represents the moving together of oscillation points
It is the distance one oscillation travels
