Final Exam Review Part III Name: 10 How do the angles of incidence and reflection compare with a flat mirror? 11. What type of mirror gives a reduced image? Which gives a magnified image? BE 12. A mass vibrates with an amplitude of 3 cm. If the mass is 0.38 kg and the spring constant is 210 N/m, what is the frequency of the vibration? 13. What is the period of a 3.9 m long pendulum with a bob of 50 kg? eldrob b 14. If a car travels toward you at a speed of 25 m/s while you are attempting to hitchhike and they honk their 700 Hz horn at you while you are standing too close to the road, what frequency will you hear? 15. The frequency of red light is 4.4X1014 Hz, what is the wavelength? 16. A 3.5 cm high object is placed 8 cm in front of a concave mirror with a radius of curvature of 35 cm. What is the location of the image and the magnification? ho = 9.5 Summary:. v = 343 m/s ho Bellwork: What type of energy involves a spring being compressed or stretched? 1. What is period? Time tocampure one cycle, measure in seconds 2. By what factor would you multiply the length of a pendulum to make the period double? 3. Draw two waves that will constructively interfere. Draw two that will be destructive. 4. Draw a standing wave with four antinodes and five nodes. 5. Draw the resultant wave for two waves that will constructively interfere. Draw the resultant for two waves that will be destructive.bonaparte 6. What type of waves are sound waves? 7. If a train is heading toward you, how will the pitch you hear be affected? 8. What type of waves does the Doppler effect happen with? 9. Which is faster: red light, violet light, gamma rays, or microwaves
