Lenses What is the difference between a converging and diverging lens? 100 Point Questions Vibrations and Waves In the standing wave shown, what is its amplitude, wavelength, and how many nodes? Sound, Light, Color What are the primary colors of the visible light spectrum? Name the colors in the visible light spectrum in order from shortest wavelength to longest. Lenses What is the difference between a converging and diverging lens? Refraction/Reflection What is the law of reflection? Draw a diagram showing the incident ray, reflected ray, normal, and the angles of incident and reflection.

Refraction/Reflection 200 Point Questions Vibrations and Waves What are the formulas to find the frequency and period? Wave speed? ( 1/f = p, 1/p = f, ws = f x wl) Sound, Light, Color What is the speed of sound? Light? (330 – 350 m/s) (3X108 m/s or 1.86 miles/s) Lenses Draw a diagram of a lens and object. Label the principle axis, focal point, focal length, object, and lens. Draw two rays from the object through the lens showing where the image is and label whether it is inverted or not. Refraction/Reflection Is a mirage a result of refraction or reflection? Page 429 refraction occurs from the differing speeds of light in the hot and cooler temps.

300 Point Questions Vibrations and Waves Sound, Light, Color Lenses What kinds of waves are sound waves and light waves? Draw the two different kinds of waves. Sound, Light, Color How does the speed of light compare in different substances such as glass, water, and diamonds? Lenses When is an image virtual or real and are they inverted or right side up? Is a real or virtual image created with a diverging lens? Refraction/Reflection A coin lies submerged at the bottom of a pan of water. Does refraction of light from the coin make it appear deeper, or shallower than it really is?

400 Point Questions Vibrations and Waves Distinguish between constructive interference and destructive interference. Constructive – effects are added together Destructive – effects cancel each other Sound, Light, Color The lines on the lenses of the eyeglasses indicate the plane of polarization through which light can pass. Which pair of glasses has the plane of polarization in the best orientation for reducing road glare while driving? Lenses Draw a ray diagram with the object before the focal point. Where is the object? Is it virtual or real? Is it magnified or smaller? Is it inverted or upright? Refraction/Reflection Explain diffuse reflection and how it is used in concert halls. Pg. 424

500 Point Questions Vibrations and Waves Sound, Light, Color Lenses Explain what happens to the waves when a supersonic jet breaks through the sound barrier. Sound, Light, Color Suppose at a concert a singer’s voice is radio broadcast all the way around the world before reaching the radio you hold to your ear. This takes 1/8th sec. If you’re close, you hear her voice in air before you hear it in the radio. But if you are far enough away, both signals will reach you at the same time. How many meters distant must you be for this to occur? V=d/t or ws=d/t Lenses Explain what near and far sighted means and how they are corrected. Refraction/Reflection What is dispersion and what is a natural example of it?
