A driver is sentenced in court for crossing an intersection in red light. For his defense, the driver claims that due to therelativistic Doppler effect he saw the traffic light as green color.Color of light depends on the light wavelength (wavelength of a wave is equal to the speed of the wave times the period).The wavelength of red light is 700 nm and the wavelength of green light is 500 nm.How fast the driver should have travelled to see red color as green color? Give answer in units of speed of light.0.32 X

Step 1: First calculate the frequency of the red light and the green light using the formula…

The half-life of a muon at rest is 1.5 micro secs. Muons that have been accelerated to a very high speed and are then held in a circular storage ring have a half-life of 6.2 micro secs. What is the total energy of a muon in the storage ring? The mass of a muon is 207 times the mass of an electron. 0.97c
When a monochromatic light source moves toward an observer, its wavelength appears to be shorter than the value measured when the source is at rest. Does this contradict the hypothesis that the speed of light is the same for all observers? Explain.
A highway patrol officer uses a device that measures the speed of vehicles by bouncing radar off them and measuring the Doppler shift. The outgoing radar has a frequency of 100 GHz and the returning echo has a frequency 15.0 kHz higher.What is the velocity of the vehicle? Note that there are two Doppler shifts in echoes. Be certain not to round off until the end of the problem, because the effect is small.
Suppose a space vehicle with a rest mass of 150 000 kg travels past the International Space Station at a constant speed of 2.6 x 108 m/s with respect to the I.S.S. When an observer on the I.S.S. measures the moving vehicle, her measurement of the space vehicle length is 25.0 m. a) Determine the relativistic mass of the space vehicle. b) Determine the length of the space vehicle as measured by an astronaut on the space vehicle.

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. answer in m/s
The fastest spacecraft ever launched was the Helios probe, which travelled approximately 70,000 m/s as it passed close to the Sun. The speed of light is 3x 10^8 m/s. Suppose the Helios probe passed by a stationary observer on Earth. The observer can see an accurate clock ticking on the side of the Helios Probe.How many seconds on Earth are equivalent to one second on the Helios probe?
George is in a spaceship, speeding away from planet Earth at , where is the speed of light in a vacuum. Anna is on George's ground crew, and she sends out a communication signal to George. Since Anna's communication signal is a radio wave, it is electromagnetic and travels at a speed of relative to Anna. From George's perspective, Anna's signal is approaching him at a speed of? c 0.5c 2c 0
Doppler Effect: This problem looks at wavelength shifts instead of frequency shifts. In this problem, AX is defined as the difference between the wavelength in the observer's frame and the source frame, and you can pick 2 to be equal to the wavelength in the source frame. a. Show that, for speeds u<
Consider a proton that has a momentum of 1.00 kg·m/s. Part (a) Calculate the relativistic parameter γ for the proton. You will have to use a 2.998 × 108 for the speed of light to get this answer correct. Part (b) What is its speed, in meters per second? Such protons form a rare component of cosmic radiation with uncertain origins.
If a sound with frequency fs is produced by a source traveling along a line with speed vs. If an observer is traveling with speed Vo along the same line from the opposite direction toward the source, then the frequency of the sound heard by the observer is c + V. fo = where c is the speed of sound, about 332 m/s. (This is the Doppler effect.) Suppose that, at a particular moment, you are in a train traveling at 33 m/s and accelerating at 1.3 m/s². A train is approaching you from the opposite direction on the other track at 35 m/s, accelerating at 1.6 m/s2, and sounds its whistle, which has a frequency of 468 Hz. At that instant, what is the perceived frequency that you hear? (Round your answer to one decimal place.) Hz How fast is it changing? (Round your answer to two decimal places.) Hz/s
