The fundamental frequency in a pipe closed at one end is 663 Hz. what is the frequency, in hertz, of the m = (2x5)+1) order harmonic? Notes: (the weird formula was just to guarantee that you always get an odd number.. i. e. if your number is 2, then the harmonic is 5. If the number in the formula is 3, then your harmonic is 7)

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. what is the best explanation of the relationship between wavelength and wave energy? a) wave energy is related only to frequency, not wavelength. b) longer wavelengths have lower frequencies but higher energy. c) the shorter the wavelength, the lower the frequency and the higher the energy. d) the shorter the wavelength, the higher the frequency and the higher the energy.
