|What is meant by the "frequency of light"? What symbol
is used for it, and what is the SI unit for frequency?
||Sketch a diagram of a wave and label its wavelength and its
||Give the equation that relates the wavelength and frequency
of a light wave to the speed of light.
||What is the frequency in hertz of blue light having a wavelength
of 425 nm?
||Ozone protects the earth's inhabitants from the harmful effects
of ultraviolet light arriving from the sun. This shielding is a maximum
for UV light having a wavelength of 295 nm. What is the frequency in hertz
of this particular wavelength of UV light?
||Radar signals are also part of the electromagnetic spectrum
in the microwave region. A typical radar signal has a wavelength of
3.19 cm. What is the frequency in hertz?
||FM radio dials are calibrated in frequency. In Ottawa,
the radio station MAGIC 100 broadcasts its FM signal at a frequency of 101.1
megahertz (MHz). What is the wavelength of this signal in meters?
||Sodium vapour lamps are often used in residential street lighting.
They give off a yellow light having a frequency of 5.09 X 1014
Hz. What is the wavelength of this signal in nanometers?
||AM radio dials are calibrated in frequency. A certain AM Brockville
radio station broadcasts at a frequency of 830 kHz. What is the wavelength
of these radiowaves expressed in meters?
||Some earthquake waves travel at 5 km/sec. What is the
wavelength of these waves if the earth tremors are 10 per second?
