A liquid lies on top of the horizontal surface of a block of glass. A ray of light traveling in the glass has speed 1.85 x 10^8 m/s, wavelength 365 nm, and frequency 5.07x 10^14 Hz. The ray is incident on the surface of the glass at an angle of 38.0° with respect to the normal to the surface. The ray that refracts into the liquid makes an angle of 44.7° with the normal to the interface between the two materials.
a) What is the speed of the light when it is traveling in the liquid?
b)What is the wavelength of the light when it is traveling in the liquid?
c)What is the frequency of the light when it is traveling in the liquid?

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.
