Unformatted text preview: THE MECHANICAL UNIVERSE Video 18. Waves Name: Mai Nguyen Class: PHYS 2425 1P1 1. What state of the art physics experiment was attempted at the end of the 17th century? measure speed of sound 2. Describe how Isaac Newton attempted to measure the speed of sound: measure the amount of time it took for the sound to get down the corridor and return using a pendulum 3. When was the first hydrogen bomb tested? 1952 What is the term for the size of a wave disturbance? amplitude Define wave period: definite time for each complete cycle What determines the pitch of a sound? frequency Write down the wave equation: v= frequency * wavelength How does an ocean wave's speed change as it approaches the shore? decrease in speed What affects the speed of a deep water ocean wave? length of wave What was the thrust of the scientific revolution during Newton's time? cast magic and the occult of of science What did Newton do to resolve discrepancies involving the speed of 4. 5. 6. 7. 8. 9. 10. 11. sound? sound travels through space of molecules between air and molecules take up space in air so add compressed linear distance to measured speed, water vapor in air also taken into account ...
