A standing wave on a stretched string has successive nodes separated by a distance of 30 cm. The amplitude of the antinodes is 12 cm at a frequency of 8 Hz.
(1) Outline what is meant by the terms
i) *node*.
ii) *antinode*.
iii) *amplitude*.
iv) *frequency*.
(2) Determine the average speed of a point on the string that is at a
i) *node*.
ii) *antinode*.
(3) State the average velocity of a point on the string that is at a
i) node.
ii) antinode.
(4) Determine the wavelength of the standing wave.
(5) Determine the speed at which waves travel along the stretched string.
