A tube is closed at one end and open at the other.
A string of length is fixed at both ends and supports standing waves. The wave speed is .
A light wave travels from air into glass.
A student shines a red laser onto a double slit and observes a pattern on a screen.
A spacecraft, while receding from Earth at , emits light at a rest frequency of . An Earth-based observer detects a redshifted signal. The frequency received on Earth is approximately .

an expression for the wavelength of the harmonic on the string.
whether the wavelength increases, decreases, or remains constant in the glass.
why the direction of the wave changes when it enters the glass.
this change using the interference equation.
the wavelength of the light as measured in the rest frame of the spacecraft.
the observed wavelength of the light on Earth.
why the observed frequency on Earth is lower than the emitted frequency, even though the light travels at the same speed in all frames.
