- Use the laws of reflection to identify which eye will see the object. Identify light rays from the object that reflect from the plane mirror into the eye. The angle of incidence must be equal to the angle of reflection.A person is standing a distance d = 1.35 m away from a mirror, which is m = 0.870 m above the ground, as shown in Figure 1. Light hits their foot, reflects off of the mirror, and enters their eye (this is how they see the reflection of their foot!). How tall are they? (Measure their height h from the ground to their eye, and don't worry about the small distance from their eye to the top of their head, which we do not have enough information to determine).= The figure is shown TO SCALE. Each block represents a 1.00 cm square. It shows a ray of light entering a rectangular piece of glass (n₂ 1.50) from air (n₁ = 1.00). Find the position (x,y in cm) where the ray exits the glass. Or, if it does not exit the glass, find the (x,y) position of the second point (the second reflection) where total internal reflection occurs. In either case, be sure to check if total internal reflection occurs. Cheese file to unload Movimuvo filo cine: 20MDY
- A person swimming underwater on a bright day and looking up at the surface will see a bright circle surrounded by relative darkness as in figure (a) below, a phenomenon known as Snell's window. Use the concept of total internal reflection and the illustration in figure (b) to show that ? = 97.2° for the cone containing Snell's window. (Submit a file with a maximum size of 1 MB.) HINTA physicist places two plane mirrors at an angle of ?1 = 55.5° to each other, as shown below. She then directs a horizontal laser beam toward Mirror 1. The beam reflects twice: first off Mirror 1, then Mirror 2. What angle ?2 will the outgoing beam make with the surface of Mirror 2?
