Physics Homework 1. A ray of light with a wavelength of 580 nanometers travels from vacuum to a substance. After itis inside the substance, its wavelength is 435 nanometers. Answer the following questions about the ray of light: a. What is the speed of the ray in the substance? b. What was the frequency of the ray in vacuum? c. What was the energy of each photon of the ray in vacuum? 2. Jerome, Maria, Kara, and Patrick are all standing in a room, as seen in the graphic below. a. Draw the location where Maria’s image is formed. b. Which person can see Maria’s image? 3. Which region of the electromagnetic spectrum most excites the interatomic bonds in molecules? You may answer with its title, its wavelength range, or its frequency range. 4. A ray of light enters a piece of glass of index of refraction nG = 1.66 as shown below. a. Calculate the angle of the ray with respect to the horizontal after its encounter with the first interface (entering the glass). b. Draw the ray’s trajectory after striking its first interface (inside the glass). c. Calculate the angle of the ray with respect to the horizontal after its encounter with the second interface. d. Draw the ray’s trajectory after striking its second interface. 5. A bug which is 4.8 mm in diameter flies in front of a converging (convex) lens with a focal length of 6.0 cm. Take the lens to be located at x = 0 cm. a. Does the lens have a positive focal length or a negative focal length? b. At the moment the bug is located at x = 7.0 cm, where is its image? c. At the moment the bug is located at x = 7.0 cm, how big is its image (diameter)? d. If the bug flies from x = 7.0 cm to x = 9.0 cm, how far does its image move? 6. Use the following diverging (concave) lens and object configuration to locate and draw the image of the object using a ray trace with all three principle rays. Physics Homework 1.
