Already know this?

Ten questions. The result tells you which lessons you may skip.

1

A standing wave on a string is formed by

2

In the standing wave \(y = [2A\sin(kx)]\cos(\omega t)\), the amplitude of the particle at position \(x\) is

3

In a standing wave of wavelength \(\lambda\), two adjacent nodes are separated by

4

Two particles of a standing wave lie in neighbouring loops. Their oscillations are

5

Which statement about the energy of a standing wave on a string is true?

6

A string \(0.50\,\text{m}\) long is fixed at both ends. The longest wavelength that can resonate on it is

7

A string fixed at both ends has a fundamental of \(150\,\text{Hz}\). Which of these is not one of its resonant frequencies?

8

A string fixed at one end and free at the other has a fundamental of \(40\,\text{Hz}\). Its next resonant frequency is

9

The tension in a stretched string is made four times as large, with the length unchanged. Its fundamental frequency

10

In Melde's experiment the prongs of a \(100\,\text{Hz}\) fork vibrate along the length of the string. The string vibrates at
