Explain how a car stereo could cause nearby windows to vibrate using what we have learned in class. Be sure to include information about the particles, sound waves, vibration, and energy.

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

What would occur if the index of refraction of a material was less than n=1? the speed of light would increase to a speed larger than the maximum speed of light in a vacuum. the light wave would not bend at all though the material. the light wave would not be able to refract and would instead reflect off of the material. the speed of light would reduce to values close to 0 m/s.

Copper has a specific heat of 0.385 j. a piece of copper absorbs 5000 j of energy and undergoes a temperature change from 100 celsius to 200 degrees celsius. what is the mass of the piece of copper?
