Optics Review Solutions 𝑛1 sin 𝜃1 = 𝑛2 sin 𝜃2 Topics Topic 1: 3 main properties of light Topic 4: Refraction Properties Electromagnetic spectrum Refraction Index of refraction (n) & Luminous, non-luminous - Methods of Calculate n Production production: incandescence, electric Describe what happens to light as it of Light discharge, fluorescence, passes into less or denser medium phosphorescence, chemiluminescence, Apparent depth, Mirage, Shimmering bioluminescence, triboluminescence, Total Internal Reflection & critical angle LED, Laser Dispersion Snell’s Law Topic 2: Laws of Reflection Topic 5: Converging lens Reflection Specular & diffuse reflection Lenses draw ray diagrams, describe SALT in Plane Describing images (SALT) - Real & virtual Diverging lens Mirrors images draw ray diagrams, describe SALT Drawing ray diagrams for plane mirrors Thin lens equation & magnification SALT for plane mirrors equation Use equations to describe image Signs for concave & convex lenses (f, di, hi, M) Applications of lenses Topic 3: Concave/converging Topic 6: The parts of the human eye Reflection draw ray diagrams, describe SALT The Eye Describe the functions of the different in Curved Convex/diverging mirrors parts Mirrors draw ray diagrams, describe SALT Myopia, Hyperopia, Presbyopia, Curved mirror equation & magnification Astigmatism equation How to correct the various eye problems Use equations to describe image Diagram of what happens when you put Understanding signs for concave & a diverging/converging lens in front of convex mirrors (f, di & hi) the eye 1. A concave mirror has a focal length of 6.0 cm. An object with a height of 0.60 cm is placed 10.0 cm in front of the mirror. a) Calculate the image distance, di. b) Calculate the image height, hi. 2. A convex surveillance mirror in a convenience store has a focal length of -0.40 m. A customer, who is 1.7 m tall, is standing 4.5 m in front of the mirror. a) Calculate the image distance, di. b) Calculate the image height, hi. 3. Calculate the speed of light in fused quartz, given the index of refraction for fused quartz is 1.46. 4. An object 8.5 cm high is placed 28 cm from a converging lens. The object forms 21 cm from the lens. a) Calculate the focal length of the lens, f. b) Calculate the image height, hi. 5. A concave mirror produces a virtual image of a flower petal 2.00 cm from the lens. Determine the magnification of the lens if the petal is 8.30 cm from the lens. 6. A lamp 10 cm high is placed 60 cm in front of a diverging lens that has a focal length of 20 cm. Determine: a) the image position. b) the image height. 7. Refer to the diagram to the right. Assume angle A measures 55˚. a) What is the measure of the angle of incidence? ____35˚____ b) What is the measure of the angle of reflection? ___35˚____ c) What is the measure of angle D? __55˚__ 8. Explain why the fish appears higher to the observer than it actually is. Light from the fish is refracted (changes direction) when it goes from water to air. It bends away from the normal since it is faster in the less dens medium (air). The observer will see the fish above the actual position since they see along the refracted ray. 9. Label the diagram below. State the functions of all the labelled parts. 10. Draw a ray diagram for an eye where you are fixing: a) myopia b) hyperopia 11. Refer to the diagram on the right. a) Explain why total internal reflection is possible. Since the light ray is going from a denser medium (glass) to a less dense medium (water). b) Calculate the critical angle for the Crown Glass-Water boundary. c) Measure the angle of incidence and draw the appropriate ray. Hint: Think about whether TIR will or will not occur. The incidence angle is 42˚ so the light ray will bend away from the normal and total internal refraction will not happen. 12. Light travels from air to glass to water. As light travels from air to glass, it strikes the glass at an angle of 28.̊ a) Calculate the angle of refractions as light passes through glass and then into water.  b) Use these values to draw the path light will take as it passes from air to glass to water. 13. Light passes from air into another material. The angle of incidence is 25˚and the angle of refraction is 19.̊ Calculate the index of refraction of the second medium. What substance is the second medium likely made up of? 14. A real image is magnified by 2 when the object is placed 22 cm in front of a lens. Determine the image distance and the focal length of the lens.
