Question 1. Question : Which wave does not need a medium? ocean wave sound wave X-ray seismic wave ripples on water Question 2. Question : Light passing through a window glass is an interaction called transmission. absorption. scattering. reflection. diffusion. Question 3. Question : The number of wave crests that go by a given point every second is called the wavelength frequency velocity amplitude Question 4. Question : The speed of light is 100,000 km/s 200,000 km/s 300,000 km/s 400,000 km/s Question 5. Question : What causes an electromagnetic wave to be emitted? writing an equation that has the wave form in it destructive interference of sound waves trying to separate electrical from magnetic phenomena acceleration of an electric charge constructive interference of any kind of wave Question 6. Question : The increase in frequency of an approaching source of electromagnetic radiation is termed the scattering effect transmission factor Doppler effect absorption spectrum Question 7. Question : Due to the Doppler effect, when a source of light approaches an observer, the light appears to be _______ than it actually is. brighter darker bluer redder Question 8. Question : The fundamental difference between electromagnetic waves and other types of waves is that electromagnetic waves move more slowly than all other types of waves. are invisible regardless of wavelength. do not experience constructive or destructive interference. transfer energy without transferring mass. all have the same wavelength. Question 9. Question : Which type of radiation can be used to sterilize medical equipment? microwave radiation ultraviolet radiation fluorescence infrared radiation radio waves Question 10. Question : Compared to microwave radiation, infrared radiation has shorter wavelengths. has longer wavelengths. is a faster wave. is a slower wave. is visible to the human eye. Question 11. Question : The Doppler effect describes how bats fly and locate their food. the way frequency of a wave appears to change from a moving source. sound wave frequency from a resting source. how dolphins navigate in the world's oceans. how humans see the colors red and blue. Question 12. Question : The complete range of wavelengths of electromagnetic radiations in the universe is the transmission factor the spectrum the scattering effect the Doppler effect Question 13. Question : If you are observing a light source moving very rapidly towards you, the Doppler effect predicts that the light will be redshifted. blueshifted. bent. transmitted. radiated.
