What does a blue shift of the light from a star indicate?
When light shifts toward the blue end of the spectrum, it is shifting in the direction of shorter wavelengths. This happens when a luminous object, such as a star, is moving toward you. This motion tends to compress the waves which it emits. Stars that are moving away from the observer will instead exhibit a red shift. The waves are stretching out, because of the motion. And because the universe is expanding, red shifts are by far the most common.

Which is hot a blue star or a red star and why?
All stars are hot. Blue stars are the hottest. The hotter a star is, the shorter the wavelength of light it emits. Blue light has a shorter wavelengths than most other colors.
Why do some clouds look pink?
Sun light travels greater distance through atmosphere at dusk than it would if its shining directly above the head . As light (mixture of different colors) travels through the atmosphere other colors (shorter light waves like blue) scatter away and you receive what is left - longer light waves of red.
Explain the differences between the waves that make up bright green light and dim red light?
Waves of bright green light have higher frequency (shorter wavelength) and higher amplitude than waves of dim red light have. For example, if the colors were red and blue, Red light has a wavelength of 750 nm and blue light has a wavelength of 500 nm. Their wavelengths will differ.
Are the light waves reflecting off a red stop sign longer or shorter than the waves reflecting off a violet colored jacket Why?
Visible light ranges from longer red light wave to shoter violet light waves in the spectrum,so the red stop sign light waves are longer.
Are green wavelengths longer than orange wavelengths?
Sound waves are much longer then light waves.
What is the ascending order of the eight electromagnetic spectrum waves base from their wavelength?
Shortest wavelength is gamma rays. Next longer wavelength is with Xrays. Then Ultraviolet, visible radiations, infra red, microwaves, radio waves with shorter wavelength and radio waves with longer wavelength
Waves diffract the most when their wavelength is Question 1 answers?
Diffraction angle is roughly proportional to wavelength (see ref.), so for a given order minimum, red diffracts more than violet light. But red is the longer wavelength, not the shorter. LONGER
Which waves have shorter wavelengths radio waves or xrays?
X-rays have shorter wavelengths than radio, heat, infra-red, visible light, and ultra-violet.
A form of energy with wavelengths longer than red light?
Infra-red waves have a wavelength which is shorter than microwaves, but still longer than visible light. Infra-red waves are basically heat energy emitted by hot objects which travel in the form of electromagnetic waves.
What color is hardest to read at a distance?
Red, especially in low contrast situations. At night blue is hard to read (the eye does not focus blue as well as longer wavelengths)
What is the diffrence between the waves that make up bright green light and dim red light?
The bright green light has a higher frequency (shorter wavelength) and a smaller amplitude than the dim red light.
In the light spectrum are red waves shorter than blue waves?
Red light waves are almost double the length of blue or violet light waves. Wavelength is inversely proportional to frequency; red light has a higher frequency than blue light.
Should red light waves have a longer wavelength th violet light waves?
Yes.
Can you see all of the radiation waves?
No. The ones you can see are regarded as "visible light". In the electromagnetic spectrum, it has a shorter wavelength than radio waves, micro waves, and infra-red. After this is visible light which goes in the order of red, orange, yellow, green, blue, indigo, violet. It has a longer wavelength than ultra-violet, x-rays and gamma-rays.
Are the wavelengths of light at the red end of the spectrum longer or shorter than those at the blue end?
Longer.
