PHY 205 Lecture Notes - Lecture 28: Primary Color, Curved Mirror, Voltage
Document Summary
Light rays that pass through a lens change direction because . Because its molecules are far apart, sound waves will travel slowly through . As the frequency of light waves increases . Light rays reflecting off a smooth surface reflect . Light rays reflecting off a rough surface reflect . The law of reflection says the angle of incidence is . the angle of reflection. An apple appears red to your eye because it . It reflects red light and absorbs all other colors. When you look in a convex mirror, the image appears . Objects in convex mirror appear smaller than it really is. When all three additive primary colors are mixed, you see the color . The amount of energy in a photon of light is proportional to the . When light moves from a material in which its speed is higher to a material in which its speed is lower, it is .
