IB SL Physics Unit 4: Waves

a propagation of energy from one position to another

_________ waves: need a medium

_________ waves: don’t need a medium

order the types of electromagnetic waves from high energy to low energy

order the types of electromagnetic waves from high frequency to low frequency

order the types of electromagnetic waves from low wavelength to high wavelength

gamma has [high/low] energy, [high/low] wavelength, and [high/low] frequency

radio has [high/low] energy, [high/low] wavelength, and [high/low] frequency

the two types of mechanical waves are _________ and __________

time it takes for the wave to repeat (seconds/wave)

period (T) is measured in

waves per unit time (waves/second = Hertz (Hz))

Frequency (f)is measured in

Speed (v) is measured in

wavelength x frequency = wavelength/period

speed of light in a vacuum (3.0×10^8 m/s)

when light (or any wave) bends due to a change in media

index of refraction

sinθ₁/sinθ₂ = n₂/n₁ = v₁/v₂

angle at which 0 refraction occurs

waves spread as they pass through an aperture or around objects

in the s = wavelength x D/d equation, the fringe width

in the s = wavelength x D/d equation, the slit distance

in the s = wavelength x D/d equation, the distance from slit to screen

a ___________ wave has nodes and antinodes; two waves that are exactly the same travel in opposite directions

a ___________ wave has a consistent amplitude and goes to infinity

exact opposite wave = π

quantity of antiphase

quantity of wave “in phase”

quantity of the antiphase of a travelling wave

quantity of a travelling wave

quantity of the antiphase of a standing wave
