107. ANS:
An oscillation that propagates in space and time is a wave. When the oscillation vibrates at right angles to the
direction of wave travel, the wave is a transverse wave. The distance between successive crests or other
corresponding of the wave is the wavelength. Wavelength is measured in centimeters, meters, or any unit of
distance. The depth of a transverse wave, at right angles to the wavelength, is the amplitude. This is the
distance from the equilibrium point to the crest of the wave (or to a trough). Wavelength is measured in any
appropriate unit of distance. The time for equal parts of a wave to pass a given point is called its period,
usually measured in seconds. How frequently the wave vibrates is called its frequency, usually measured in
hertz. One hertz is one vibration per second. The wave speed is the speed at which the wave travels, measured
in meters per second or any other appropriate unit of speed. The period and frequency of a wave are
reciprocals. For example, a 2-hertz wave has a period of second a 3-hertz wave has a period of second
and so on. Wave speed is equal to wavelength multiplied by frequency.

108. ANS:
In a transverse wave, oscillations are perpendicular to the wave velocity. Oscillations in a longitudinal wave
are forward and backward in the direction of the wave’s velocity. Waves on a string, waves on the surface of
water, and electromagnetic waves are transverse waves; sound waves and waves along the axis of a coil
spring are longitudinal waves.

Radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays are all
part of the electromagnetic spectrum. Their approximate frequencies are 103 to 106 Hz, 107 to 1010 Hz, 1011 to
1014 Hz, 1014 Hz, 1015 to 1016 Hz, 1017 Hz, and 1018 Hz respectively. Radio waves are emitted at radio
broadcast towers, and microwaves in microwave ovens. Microwaves are also used to transmit TV and
information signals across Earth and between Earth and satellites. Infrared, visible, and ultraviolet waves are
found in sunlight. X-rays are found in medical laboratories and also are emitted from most stars and galaxies.
Gamma rays are emitted by nuclear reactions in laboratories and in reactors.

111. ANS:
Refraction is the bending of light or sound as it passes from one medium to another. Light and sound are
refracted because they travel at different speeds in different media. Sound refraction occurs at concerts on hot
summer days when it is often difficult to hear the band. It also is responsible for noises traveling better across
water at night than in the daytime. Lenses work because of light refraction. A pencil in a glass of water will
appear broken because of light refraction.
