Question 1
The distance between
successive wave crests
defines the ________ of a
wave.
1) wavelength
2) frequency
3) period
4) amplitude
5) energy
Light can range
from shortwavelength
gamma rays to
long-wavelength
radio waves.
Question 2
Which of these is
NOT a form of
electromagnetic
radiation?
1) gamma rays
2) infrared
3) sound
4) visible light
5) radio
Question 2
Which of these is
NOT a form of
electromagnetic
radiation?
1) gamma rays
2) infrared
3) sound
4) visible light
5) radio
Sound comes from
pressure waves; all
others are types of
EM radiation of
different
wavelengths.
Question 3

from space reach the
surface of Earth?
1) radio & microwaves
2) X rays & ultraviolet light
3) infrared & gamma rays
4) visible light & radio waves
5) visible & ultraviolet light

surface of Earth?
1) radio & microwaves
2) X rays & ultraviolet light
3) infrared & gamma rays
4) visible light & radio waves
5) visible & ultraviolet light
Earth’s
atmosphere
allows radio
waves & visible
light to reach the
ground.
Question 4
The frequency at
which a star’s
intensity is greatest
depends directly on its
1) radius.
2) mass.
3) magnetic field.
4) temperature.
5) direction of motion.
Question 4

which a star’s
intensity is greatest
depends directly on its
Wien’s Law means
that hotter stars
produce much more
high frequency light.
1) radius.
2) mass.
3) magnetic field.
4) temperature.
5) direction of motion.
