A tube is closed at one end and open at the other.

the fundamental mode of the standing wave in the tube.

the position of the node and antinode.

the length of the tube in terms of the wavelength.

A string of length $L = 1.0\ \text{m}$ is fixed at both ends and supports standing waves. The wave speed is $v = 120\ \text{m s}^{-1}$ .

A light wave travels from air into glass.

the term “refraction”.

what happens to the speed of light as it enters the glass.

A student shines a red laser onto a double slit and observes a pattern on a screen.

and the intensity pattern observed.

how the fringe spacing would change if the slit separation is increased.

A spacecraft, while receding from Earth at $0.85c$ , emits light at a rest frequency of $5.00 \times 10^{14}\ \text{Hz}$ . An Earth-based observer detects a redshifted signal. The frequency received on Earth is approximately .

an expression for the wavelength $\lambda$ of the $n^\text{th}$ harmonic on the string.

In a pipe that is closed at one end and open at the other, only certain harmonics are observed. why some harmonics are missing in such a tube.

the frequency of the fourth harmonic for the string.

the standing wave pattern corresponding to the second and fourth harmonic on the string.

the harmonic series for a string fixed at both ends and a pipe closed at one end.

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.
