Chapter #5 Flashcards
Which form of electromagnetic radiation is absorbed by carbon dioxide and water vapor in our atmosphere?
infrared
Which form of electromagnetic radiation would be blocked in the stratosphere by ozone?
ultraviolet
Of all forms of electromagnetic radiation, the one with the lowest frequency is
radio waves
The two forms of electromagnetic radiation that penetrate the atmosphere best are
visible and radio waves
X-ray telescopes are located in orbit around the Earth because
X-rays don’t reach the surface of Earth
The number of waves passing the observer per second is
the frequency in Hertz
Electromagnetic radiation with a wavelenght of 700 nm would be
red light
The visible color of electromagnetic radiation that has the shortest wavelength is
violet
Colors appear different to us because of their photons’ different
frequencies
If a wave’s frequency doubles, its wavelength
is halved
The Doppler Effect is a phenomenon that allows one to measure an object’s
radial motion
If a beam of blue light has a wavelength of 400 nm is emitted by an object moving away from you at 1% of the speed of light, what wavelength would you see from this light from this light?
396 nm
Both sound waves and electromagnetic radiation
transfer energy
What does the phenomenon of diffraction demonstrate?
the wave nature of light
What does the phenomenon of interfernce demonstrate?
the particle nature of the photon
