__EM
SPECTRUM, WAVELENGTH, FREQUENCY, AND ENERGY__

1.)
Look at the EM spectrum on p. iv of the reference
tables to answer this question.

As you move across the visible light
spectrum from red to violet…

(A) Does the wavelength
increase or decrease?

(B) Does the frequency
increase or decrease?

(C) Does the energy
increase or decrease?

2.)
A beam of microwaves has a frequency of 1.0 x 10^{9} Hz. A radar beam has a frequency of 5.0 x 10^{11}
Hz.

Which type (microwave or radar)…

(A) has a longer
wavelength?

(B) is closer to visible
light on the EM spectrum?

(C) is closer to x-rays in
frequency value?

3.)
What is the frequency of an EM radiation wave if its wavelength is 3.6 x 10^{-9}
meters?

4.)
A beam of EM radiation has a wavelength of 4.257 x 10^{-7} cm. What is its frequency?

5.)
A photon of light has a wavelength of 3.20 x 10^{5} meters. Find…

(A) the
frequency

(B) the
energy

(C) the
region of the EM spectrum/type of radiation

6.)
A photon has an energy of 4.00 x 10^{-19}
J. Find…

(A) the
frequency

(B) the
wavelength

(C) the
region of the EM spectrum/type of radiation

7.)
A bright line spectrum contains a line with a wavelength of 518 nm. Determine…

(A) the
wavelength in meters

(B) the
frequency

(C) the

(D) the color

*8.) Cobalt-60 is an artificial radioisotope
that is produced in a nuclear reactor for use as a gamma ray source in the
treatment of certain types of cancer. If
the wavelength of the gamma radiation from a cobalt-60 source is 1.00 x 10^{-3}
nm, calculate the energy of a photon of this radiation.
