Question
- fill in the names of the types of waves in the electromagnetic spectrum below. be sure to indicate the frequency and wavelength ranges for each type of wave. color the visible spectrum. label the low and high energy, frequency and wavelength ends of the spectrum.
diagram: visible spectrum, electromagnetic spectrum with boxes, and labels for high/low energy, frequency, wavelength
- using the above electromagnetic spectrum that you just created, answer the following questions:
a. what color has the longest wavelength? red (written)
b. what electromagnetic wave has the shortest wavelength? gamma rays (written)
c. what color has the highest energy? purple (written)
d. what electromagnetic wave has the highest energy? gamma rays (written)
e. what color has the lowest frequency? red (written)
f. what electromagnetic wave has the highest frequency? gamma rays (written)
g. consider radio, infrared, visible and x - ray radiation. put them in order of increasing wavelength: radio, infrared, visible, x - ray (written)
h. consider red, green, blue and purple visible light. put them in order of increasing frequency: red, green, blue, purple (written)
Question 5 (Filling the Electromagnetic Spectrum):
The electromagnetic spectrum (from longest to shortest wavelength, lowest to highest energy/frequency) includes: Radio Waves, Microwaves, Infrared, Visible Light (Red, Orange, Yellow, Green, Blue, Violet), Ultraviolet, X - Rays, Gamma Rays.
- For the left side (low energy, low frequency, long wavelength): Radio Waves, Microwaves, Infrared.
- Visible Light: Red, Orange, Yellow, Green, Blue, Violet (from left to right in the visible box, with Red on the left - most of visible, Violet on the right - most).
- For the right side (high energy, high frequency, short wavelength): Ultraviolet, X - Rays, Gamma Rays.
Question 6:
a.
In the visible spectrum, wavelength decreases from Red to Violet. So Red has the longest wavelength.
In the electromagnetic spectrum, Gamma Rays have the shortest wavelength (and highest energy/frequency).
In visible light, energy increases with frequency (and decreases with wavelength). Violet (or Purple, as a close approximation) has the highest energy.
