White light, with uniform intensity across the visible wavelength range of 400 nm - 690 nm, is perpendicularly incident on a water film, of index of refraction 1.33 and thickness 300 nm. At what wavelength (in nanometers) is the light reflected by the film brightest to an observer

Which of the following would not be taken into consideration when describing the quality of a sound

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.
