  1. Welcome to Physics& 123! Write your name on a popsicle stick • On the index card, write: • your name • your preferred email address • your phone number (cell preferred) • the last Math class you took • the last Science class you took • the last English class you took • your major/intended career

  2. Module 4: Lab 1 Objectives • To discover how light spreads out from a point source • To examine quantitatively how the intensity of light varies with distance from a point source • To discover how light rays can be used to represent light as it spreads out from a point source • To discover the origin of parallel rays of light • To examine how we are able to see objects--how the light from objects reaches our eyes • To compare the light from point and extended sources • To observe qualitatively the interaction of light with the surface of a transparent object

  3. Jeff Goldblum is checking his reflection in a mirror. How much of himself can he see in the mirror?

  5. Two plane mirrors form a right angle. How many images of the ball can you see in the mirrors?

  6. Light from a laser is shone into a fish tank at an angle of i=30o. Neglecting the glass, at what angle will the light travel through the water?

  7. 1. The figure shows an object O in front of a plane mirror. Use ray tracing to determine from which locations A-D the object's image is visible. 2. A ray of light traveling through air encounters a 1.2 cm thick sheet of glass at a 45o angle of incidence. How far does the light ray travel inside the glass before emerging on the far side?
