A transverse wave with a frequency of 125 Hz is traveling in the x-direction. An illustration of a transverse wave with the distance from the high point to the low point labeled 5 centimeters and the vertical distance from the high point of the wave to the low point of the wave labeled 12 m. How long will it take this wave to travel 3000 m in the x-direction? 0.42 seconds 2.0 seconds 2.4 seconds 4.8 seconds

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
