waves made by vibrating electric charges correct answers electromagnet waves
the range of electromagnetic waves that you detect with your eyes correct answers visible light
a massless bundle of energy that behaves like a particle. correct answers photon
electromagnetic waves with wavelengths between 0.1 mm and 30 cm correct answers microwave
electromagnetic waves with wavelengths from about 400-billionths to 10-billionths of a meter
correct answers ultraviolet waves
electromagnetic waves between about 10-billionths of a meter and 1-trillionths of a meter correct
answers x-rays
electromagnetic waves shorter than about 100-trillionths of a meter correct answers gamma rays
electromagnetic waves with wavelengths longer than 10 cm correct answers radio waves
electromagnetic waves with wavelengths between about 1-thousanth meter and about 700-

Would a vibrating proton produce an electromagnetic wave? Would a vibrating neutron? correct
answers Proton yes, because it is a charged particle; Neutron no, because it is not a charge
particle
Compare the frequency of an electromagnetic wave with the frequency of the vibrating charge
that produces the wave. correct answers They are equal
Describe how electromagnetic waves transfer energy to matter. correct answers by causing
charged particles within objects to move
Explain how an electromagnetic wave can travel through space that contains no matter. correct
answers An electromagnetic wave is made of vibrating electric and magnetic fields that
continually induce each other; matter is not needed for this to occur.
Would a stationary electron produce an electromagnetic wave? Would a stationary magnet?
Explain. correct answers No; No; they have to move to produce a wave.

Light travels at about 300,000 km/s. How many minutes does it take an electromagnetic wave to
travel from the sun to the earth, which is about 150,000,000 km away? correct answers 8.3
minutes
, Compare and contrast the properties and uses of radio waves, infrared waves, & ultraviolet rays.
correct answers All are electromagnetic waves; radio waves are very long & are used for
communications; Infrared waves are long and are used for thermal imaging; Ultraviolet waves
are short and are used for purification & forensic
A mug of tea is heated in a microwave oven. Explain why the tea gets hotter than the mug.
correct answers water (tea) absorbs more energy (microwaves) than ceramics (mug) so it gets
hotter
What are the beneficial and harmful effects of human exposure to ultraviolet rays? correct
answers Beneficial - Purification & vitamin D production; Harmful - damage proteins, DNA
molecules, skin, & cause cancer.
What objects produce electromagnetic waves, with descriptions? correct answers remote controls
use infrared rays; microwaves cook our food; Lights give us light
How could infrared imaging be used to find a lost hiker? correct answers When you scan the area
the hiker's body would appear as a warm dot, unless dead.
