Helo am desperate answer quick will give brainliest what determines how high-pitched or low-pitched sounds are? (Select all that apply.)
the distance between crests
the wavelength of a sound
the volume of the sound
the direction of the sound

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?
