Unit 3 Packet 1 Review

Front

What is the equation that relates energy, frequency, and speed of an electromagnetic wave?

Back

E = h(c/λ)

Front

What is the equation that relates the speed of light, wavelength, and frequency of an electromagnetic wave?

Back

c = λf

Front

Calculate the wavelength of the yellow light emitted by the street light, if the frequency of the radiation is 5.10x10^14Hz.

Back

5.88 x 10^-7 m

Front

Which of the following are in the correct order from least to greatest energy? Radio, Visible, Gamma

Back

Radio, Visible, Gamma

Front

What does energy have to do with wavelength and frequency?

Back

The shorter the wavelength the more energy the wave has.

Front

What is the speed of light in a vacuum?

Back

c = 3.0 x 10^8 m/s

Front

What is Planck's constant?

Back

h = 6.626 x 10^-34 J·s

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What type of electromagnetic radiation has the longest wavelength?

Back

Radio waves have the longest wavelength.

Front

What type of electromagnetic radiation has the highest energy?

Back

Gamma rays have the highest energy.
