Chapter 11 - Waves 1 Flashcards
Define a progressive wave.
Define a transverse wave.
Define a longitudinal wave.
What features do transverse waves have?
What features do longitudinal waves have?
Define displacement.
Define amplitude.
Define wavelength.
Define period (of oscillation).
Define frequency.
Define wavespeed.
Describe and label a transverse wave graph.
Describe and label a longitudinal/compressive wave graph.
Define the wave equation (wave speed).
Define frequency, in terms of a time period of a wave.
Define phase difference.
How can you tell if two particles are in phase?
How can you tell if two particles are in antiphase?
Under what conditions does reflection occur?
What is the law of reflection?
The law of reflection applies whenever waves are reflected. It states that the angle of incidence is equal to the angle of reflection.
Under what conditions does refraction occur?
Define diffraction.
Define Polarisation.
Define intensity of light, and give the general formula of light intensity.
Give the formula of intensity of light in terms of a point sphere.
What is the relationship between intensity and amplitude?
State the sizes of each EM wave.
What is the equation for the speed of light.
The speed of light = frequency of the EM wave x wavelength.
Define the equation for refractive index.
State Snell’s Law.
What are the two conditions for Total Internal Reflection.
What is the formula for the critical angle?
C is the Critical Angle, and n is the refractive index of the material.
