Abeam of light is traveling in air and strikes a material. the angles of incidence and refraction are 63.0° and 47.0° respectively. obtain the speed of light in the material.

Speedd of the light in the medium is

Explanation:

According to Snell's law we have

Since incidence medium is air thus we have

Applying values we get

Now we know that speed of light in any medium is given by

where is the refractive index of the medium and 'c' is the speed of light in vacuum

Thus upon applying values we get

explanation:

areas w steep slopes, west coast, rocky mountains, and appalachian mountains

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
