Idon't understand any of this, can someone me go through 1) the average chemical bond in your body requires about 5.8x10⁻¹⁹ joules of energy to break it. a) what is the frequency of a photon carrying this amount of energy? b) what is the wavelength of photon carrying this amount of energy? c) what category of electromagnetic radiation does this fall? use the table below as a guide. (table) gamma ! x-ray ! ultraviolet ! visible ! infrared ! < 1x10⁻¹¹ m ! 1x10⁻¹¹-1x10⁻⁸ m ! 1x10⁻⁸-3.8x10⁻⁷ m ! 3.8x10⁻⁷-7x10⁻⁷ m ! 7x10⁻⁷-1x10⁻³ m! radio > 1x10⁻³ m

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
