- A ray of yellow light crosses the boundary between glass and air, going from the glass into air. If the angle of incidence is 20°what is the angle of refraction?(a) A narrow beam of light is incident on the left side of the prism shown in the figure below. The prism is a right triangle, with two of its angles measuring 45°. The transmitted beam that exits the hypotenuse of the prism makes an angle of 8 = 22.2° with the direction of the incident beam. What is the index of refraction of the prism? (Round your answer to at least two decimal places.) 7 45.0° Ⓡ (b) What If? In part (a), we assumed the beam was monochromatic. Consider instead the case where the beam was composed of white light. Because the index of refraction differs for different wavelengths, the white light would be dispersed into constituent colors. Assume the index of refraction for blue wavelengths is 1.01n and for red wavelengths it is 0.99n, where n is the index of refraction found in part (a). What is the angular spread (in degrees) between red and blue light exiting the prism?A ray is incident upon a reflective surface at an angle of θi=28.2∘relative to the direction normal to the surface (see image below to help visualize the situation). What is the angle of the reflected ray (θr) relative to the normal direction (in degrees)?
- You are a detective interviewing someone who says that (while sitting on a porch that you know to be 600ft away) he saw the masked suspect commit the crime in broad daylight. "How do you know it was the suspect?" you ask. "I clearly saw the 'MOM' that is tattooed on his upper arm." "You're sure it was that particular tattoo and not some other tattoo?" "Yes, I'm sure," The witness replies. The suspect's tattoo has letters that are 6cm tall. Is the witness credible, or might he be framing the suspect? Justify your response and any estimates you might make.The figure below shows a light ray traveling in a slab of fluorite surrounded by air.
