Lesson 1: Electromagnetic Radiation 1. A planet is 7.60 x 1012 m from Earth. How long will it take a radio signal to travel to this planet and back? Lesson 2: The Speed of Light 2. Using the Michelson-like apparatus diagrammed below, the observer found that in order to observe the return light ray, the mirror had to rotate at 707.1 Hz. What is the speed of light calculated from this experiment? observer A Stationary reflecting mirror 7v Rotating six- sided mirror light source 35.0 km Lesson 3: Reflection 3. A 6.0 cm tall object is placed 40 cm in front of a concave mirror with a radius of curvature of 60 cm. A. What is the image distance? B. What is the size of image produced? C. Describe the properties of the image (real/virtual | upright/inverted) 4. An object located 40 cm in front of a mirror produces an upright image 20 cm from the mirror. A. What is the radius of curvature for the mirror? B. What type of mirror is it? 5. An object located in front of a concave mirror with a radius of curvature of 80 cm produced an inverted image that is three times the size of the object. What is the object's distance from the mirror?6. A beam of light strikes the surface of water with an incident angle of 60". Some of the light reflects off the water and some refracts into the water. If water has an index of refraction of 1.33, determine the angle of refraction. 7. What is the wavelength of light in water if the wavelength in air is 570 nm?PHYSICS DATA SHEET Constants Prefixes Used with SI Units Particles Acceleration Due to Gravity Exponential Charge Mass Near Earth........ lag| =9.81 m/s2 Prefix Symbol Value Gravitational Constant ......
