- Based on how it refracts light, what would you expect images formed by a concave lens to look like? The same as the objects that they are images of Reversed Smaller MagnifiedA light ray passes through a glass lens, shown in cross section in the figure below. Find the angle of incidence ?. (Take theta1 = 33°, theta2 = 23°, and theta3 = 27°.)A man shines a flashlight from a boat into the water, illuminating a rock as in the figure below. What is the angle of incidence ?1 (in degrees)?
- 24. Which one is the correct refracted ray for the incident blue ray? O Green Red O Both O NoneAs shown in the diagram below, two mirrors meet at an angle, ?2 = 154°. The red lines indicate the path a light ray has taken with ?3 = 2°. Determine ?1. ?1 =If a point source with intensity of 200 candela is 10 ft. above a 2 ft2 surface, what is the illumination level at the center of the surface?
- You put a 1.34-cm high candle 9 cm in front of a lens and you see an image with di = -6.09 cm. On your paper, draw: the lens (draw this as a diverging or converging lens based on the focal length) the optical axis the candle three rays from the object to the image. These rays should reach the lens traveling: parallel to the axis toward the center of the lens toward the focal point (note: for a diverging lens, this would be the focal point on the opposite side as the object) the image a box with the following information about the image: real or virtual upright or inverted magnified, reduced or same size In the space below enter the height of the image in centimetres. If it is inverted, the height will be negative.Why is the angle of the ray that leaves the trapezoid relative to the ray that enters it?What is the difference between the critical angle and Brewster’s angle?
