Doppler Doppler effect Light

AI Thread Summary

When a star moves toward Earth, its emitted light experiences blue shift, resulting in a decrease in wavelength. If violet light with a wavelength of 400 nm is blue shifted to 1 nm, it transitions into the X-ray spectrum. This phenomenon demonstrates how the Doppler effect on light can lead to significant changes in the observed wavelength. Consequently, the light received on Earth from such a star would indeed be classified as X-rays. Understanding this effect is crucial for astrophysics and the study of stellar movements.

If a star races toward Earth the emitted light will be blue shifted. If the violet light produced from the star has a wavelength of 400 nm and it is blue shifted to 1 mn, does this light now exist as x-rays (on earth)?

Yes, the light received at Earth will fall in the X-Ray band.

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.
