Light is emitted by a distant star at a frequency of 4.56 x 10^24 Hz. a) If the star is moving toward Earth at a speed of 2750 km/s, what frequency light will be detected by observers on Earth? b) Is this considered a Blue shift or a Red shift?
The distance from earth to the nearest star is about 4 x 1016 meters. How long would it take a radio signal traveling at the speed of light, 3.0 x 108 m/s, to make a one-way trip to this star?
A speeder tries to explain to the police that the yellow warning lights she was approaching on the side of the road looked green to her because of the Doppler shift. How fast would she have been traveling if yellow light of wavelength 576.6 nm had been shifted to green with a wavelength of 562.3 nm? Note: For speeds less than 0.03c, the equation below will lead to a value for the observed frequency accurate to approximately two significant digits. fO ≈ fS (1 ± u/c) if u < c what is the frequency in m/s?
A speeder tries to explain to the police that the yellow warning lights she was approaching on the side of the road looked green to her because of the Doppler shift. How fast would she have been traveling if yellow light of wavelength 576.6 nm had been shifted to green with a wavelength of 564.2 nm? Note: For speeds less than 0.03c, the equation below will lead to a value for the observed frequency accurate to approximately two significant digits. fo=fs(1+4) m/s if u < c
A speeder tries to explain to the police that the yellow warning lights she was approaching on the side of the road looked green to her because of the Doppler shift. How fast would she have been traveling if yellow light of wavelength 577.5 nm had been shifted to green with a wavelength of 563.7 nm? Note: For speeds less than 0.03c, the equation below will lead to a value for the observed frequency accurate to approximately two significant digits.
After Dragonfly lands and is unfolded from its carrier, it flies away at 3.368 m/s. We know that the buzzing sound it makes is at 499.07 Hz, thanks to laboratory testing. The microphone on the stationary carrier detects a frequency of 492.8 Hz. What is the speed of sound at the surface of Titan?
A chimpanzee is standing not too far from a tall cliff. He lets out a loud bark and is startled to hear an echo from the cliff 0.830 seconds later. How far away is the cliff? Take the speed of sound to be 331 m/s.
You are standing still at a railroad crossing when the driver of the train sounds its whistle. You hear the whistle at 390 Hz while the driver hears it at 410 Hz. What is the relative motion between you and the train? The train is moving in a circle at a constant distance from you. The train is moving away from you. The train is moving towards you. Neither you nor the train is moving.
1. The nearest stars, apart from the Sun, are light-years away from Earth. If we are to investigate these stars, our space ships will have to travel at an appreciable fraction of the speed of light. (a) You are in charge of estimating the energy required to accelerate a 10,000 kg capsule from rest to 10 percent of the speed of light in one year. What is the minimum amount of energy that is required? (b) Compare your estimate to the amount of energy that the United States uses in a year about 5 x 1020 ). (c) Estimate the minimum average power required of the propulsion system. ((a) 4.5 x 1018 J, (b) 0.9%, (c) 1.4 x 1011 W)
Lightning storm creates both lightning and thunder. You see the lightning almost immediately since light travels at 3 × 108m · s−1. After seeing the lightning, you count5 s and then you hear the thunder. Calculate the distance to the location of the storm. Convert into kilometers.
You get pulled over for running a red light. $500 fine. When you get to court, you explain that it wasn't your fault. You were traveling toward the light, and the red light blue-shifted to green. The judge (who knows physics) offers to drop the red light violation (saving you $ 500), if you will pay a fine for speeding of $ 1 for every mile/hour over the speed limit (55 mph). How much would you pay for speeding, and is it a better deal than the red light ticket? (Assume green is about 500 nm and red is about 650 nm)
A car is traveling towards an observer at a speed of 23m/s. The car sounds it’s horn which has a frequency of 400hz. If the air temperature that day was 17° c, what frequency did the observer hear?
