Hypothetically if your in a jet or spaceship & are shining a green laser pen out the window how fast must you travel to cause the green light (570 nm) to change into low energy blue light (475 nm)
You need to use the relativistic Doppler formula:Moviemann345 said:fo = fv/(v ± vs)? This isn't a homework problem & I am not in a physics class, I was just curious
As an object moves at a faster speed, its emitted light shifts towards the blue end of the visible light spectrum. This is known as the Doppler effect, where the wavelength of light appears shorter as an object moves towards an observer.
Yes, the speed of an object can change the color of light it emits. As an object's speed increases, the wavelength of light it emits becomes shorter, resulting in a shift towards the blue end of the spectrum. This is also true for objects moving away from an observer, as the light emitted will shift towards the red end of the spectrum.
The shift in light color may not always be noticeable when an object is moving at high speeds. This is because the Doppler effect is only significant for objects moving at very high speeds, such as those close to the speed of light. For objects moving at slower speeds, the shift in light color may be too small to detect with the naked eye.
As an object approaches the speed of light, the shift in light color becomes more significant. At the speed of light, the Doppler effect causes the wavelength of light to become infinitely short, resulting in a shift towards the ultraviolet end of the spectrum. However, objects with mass cannot reach the speed of light, according to Einstein's theory of relativity.
Yes, besides speed, the color of light can also be affected by the object's temperature and the medium through which the light is passing. As an object's temperature increases, the color of its emitted light shifts towards the blue end of the spectrum. Additionally, light passing through different mediums, such as water or air, may also cause a shift in color due to refraction.
