3a. Light traveling in air encounters a flat side of a solid block of a transparent material that is completely immersed in air, i.e., it is completely surrounded by the air. Some of the incident light is reflected back into the air and some enters the material. If the angle of incidence that the light makes at the flat side is 16.8 degrees, what is the angle that the light is reflected back into the air relative to a perpendicular...
Question 2 20 points A ray of light from air is incident on the surface of the water and is reflected and refracted. If the angle of refraction is 30° and the index of refraction for water is 1.33 what is the angle in degrees between the reflected and refractad rays?
3. (15 points) A light ray is traveling horizontally through air and hits the rectangular glass block shown to the right. The block has a triangular, air-filled cavity within it. You may take the index of refraction of air to be mair 1 and the index of refraction of glass to be nglass 1.5 40° く enters the glass block. Sketch this refracted ray on the diagram to the right. a. Calculate the angle of traction when the light ray...

A beam of white light is incident on the surface of a diamond at an angle θa. (Figure 1) Since the index of refraction depends on the light's wavelength, the different colors that comprise white light will spread out as they pass through the diamond. For example, the indices of refraction in diamond are nred=2.410 for red light and nblue=2.450 for blue light. Thus, blue light and red light are refracted at different angles inside the diamond, as shown in...
The index of refraction for red light in water is 1.331 and that for blue light is 1.340. If a ray of white light enters the water at an angle of incidence of 61.55o, what are the underwater angles of refraction for the blue and red components of the light? (Enter your answers to at least two decimal places.) (a) blue component (b) red component Need Help? Read It The light beam shown in the figure below makes an angle...
Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
