1. A 5.0 Hz water wave, travelling at 30 cm's in deep water, enters shallow water so that the angle between the
incident wave in the deep water and the boundary is 50". If the speed of the wave in the shallow water is 27
cm/'s, what is
(a) the angle of refraction in the shallow water
(b) the index of refraction for the media
(c) the wavelength of the wave in the shallow water
2. Red light with a wavelength of 650 nm travels from air into glass (n = 1.51).
(a) What will its velocity be in the glass's
(b) What will its wavelength be in the glass?
Problem (Inq-5)
3. A student creates a two-point source interference pattern in a ripple tank with two sources operating in phase.
A point on the eighth nodal line is 1.25 m from the centre of the two sources and 48.0 cm from the
perpendicular bisector of the two sources. If the source separation is 2.75 cm, find the wavelength of the
waves.
. Red light with a wavelength of 725 nm enters glass with index of refraction 1.52. Located within the glass
block is a single slit, and a screen is placed 1.25 m away. If the width of the slit is 18.5 um, find the width of
the central maximum (a) in degrees and (b) in centimeters.
5. A soap film in air has a thickness of 175 nm. If the index of refraction of the soap film is 1.35, what colour of
light will be transmitted through? (i.e., What colour does the bubble appear to be from the other side?)
6. A student performs Young's double-slit experiment using a slit separation of 21.6 um. A screen is placed 2.50
m from the centre of the sources such that a point on the fifth nodal line is 37.5 cm from the centre of the
interference pattern. Find the wavelength of the light used and identify its colour.
