Chapters 10 and 11 quiz

What type of waves are these? AB

Matching - Wave properties A.Wavelength B.Frequency C.Amplitude D.Speed 1.the number of wave crests which pass a point per second 2.the rate at which the wave travels away from the source 3.the distance between similar parts of a wave 4.the maximum amount the medium is disturbed from equilibrium

Wave Properties: Speed  The speed of sound is 1/5 mile/sec You hear the thunder 10 seconds after seeing the lightning. How many meters away is the lightening?

If you cut the wavelength in half and the speed stays the same, the frequency will a)Double b)Be cut in half c)Quadruple d)Remain unchanged Speed = frequency × wavelength

Matching – Crude wave behavior descriptions A.Reflection B.Refraction C.Diffraction D.Interference 1.Bending when the medium changes 2.Bouncing off an interface 3.Combining waves to strengthen or weaken the total wave 4.Bending around corners

T/F  A wave diffracts much more when the incoming wavelength is much smaller than the opening.

Electron Source  Electromagnetic radiation is given off whenever electrons __________.

Wave Particle Duality  Why is light both like a wave and a particle?
