Total questions: 86
Worksheet time: 1hrs 5mins
Fill in the blank: A (a) is a continuous line that shows a range of measurements along which a 'type' or 'kind' can be placed.
The EM spectrum shows:
a. How color is related to amplitude
b. The continuous range of visible light waves
c. The continuous range of all the electromagnetic waves
d. How joules of energy change over time
Which statement is most accurate?
a. Visible light waves and x rays are actually the same phenomena, differing only in frequency and wavelength
b. Visible light waves and x-rays are very different phenomena, because they differ in frequency and wavelength
c. Visible light waves are different and separate from the rest of the EM spectrum because we can see them
d. Visible light waves are just an illusion and are made up
According to the image to the right, the two wavelengths that make it through the atmospheric window are:
(a)
Why would scientists send the Chandra X-ray observatory into space (why not observe x-rays from earth?)
A (higher/lower) frequency means more energy, more energy means (more/less) danger to human cells. Radio waves are (safe/not safe) for humans. They are an example of (high frequency/low frequency) radiation. Gamma rays, though, have (higher/lower) frequency, and they are (not at all/generally considered) dangerous to human cells.
higher, more, safe, low frequency, higher, generally considered
lower, more, not safe, low frequency, higher, not at all
As amplitude of a set of light waves increases, ________________. (What increases or decreases?)
Color increases in frequency
Color decreases in frequency
Brightness increases
Brightness decreases

This wavelength humans can see.
(a)
This wavelength can move through most human tissue but is blocked by bone. It is used in medical imaging.
(a)
This wavelength is the highest energy of the ones presented to the class, it comes out of exploding stars and some radioactive material.

(a)
This wavelength is on the lower end of energy on the spectrum. It is used so cell phones can communicate with cell phone towers and it can make water molecules move faster, heating up our food.
(a)
This wavelength is visible to some animals like some birds, fish, and insects. It is a little more energetic than visible light and can cause skin cancer.
