Which color has the longest wavelength and shows that a star is moving away from us?
It's not that a particular color has the longest wavelength. The wavelength BECOMES longer when a star moves away from us. Red light has a longer wavelength than blue, for example.
When a star is red is its waves longer or shorter?
When a star is red, its waves are longer. Red light has a longer wavelength compared to other colors in the visible spectrum.
Is the color of star an effect of its temperature?
Yes. The apparent colour of a star is related to the peak wavelength of the light it emits. According to Wien's displacement law (look it up in Wikipedia) the peak wavelength is inversely proportional to the temperature. The higher the temperature, the shorter the peak wavelength. Wavelength decreases as one moves from red to blue in the visible spectrum, so a red star is cooler than a blue one.
Which color has highest wavelength?
Red has the highest wavelength among the visible colors.
What can you infer about a star that exhibits a red shift in its spectra?
A red shift in a star's spectrum indicates that the star is moving away from us. This is due to the Doppler effect, where the wavelength of light is stretched as the source moves away, shifting it towards the red end of the spectrum. This can be used to determine the star's velocity and direction of movement.

When a star is red, its waves are longer. Red light has a longer wavelength compared to other colors in the visible spectrum.
What is the relationship between the color of the star and temperature of a star?
The color of a star is related with the wavelength of the light observed. Wien's Law states that: Peak Wavelength x Surface Temperature = 2.898x10-3 Peak Wavelength is the wavelength of the highest intensity light coming from a star.
Is the color of star an effect of its temperature?
Yes. The apparent colour of a star is related to the peak wavelength of the light it emits. According to Wien's displacement law (look it up in Wikipedia) the peak wavelength is inversely proportional to the temperature. The higher the temperature, the shorter the peak wavelength. Wavelength decreases as one moves from red to blue in the visible spectrum, so a red star is cooler than a blue one.
Why does a red star shine red?
Stars emit light because they are hot. When a hot object glows the color of light it emits depends on the temperature. The higher the temperature, the shorter the wavelength of light. The shortest wavelength of visible light is red Therefore the stars with the lowest temperature glow red.
Which color has highest wavelength?
Red has the highest wavelength among the visible colors.
The color with the largest wavelength is?
Of the seven colors in the rainbow (red, orange, yellow, green, blue, indigo, and violet) the color with the longest wavelength is red.
Which star will emit the shortest wavelength of its peak frequency?
The star emitting the shortest wavelength of its peak frequency will be a star with high temperature, such as a blue star. This is because the wavelength of light emitted by an object is inversely proportional to its temperature according to Wien's law.
What color out of red yellow and green has the shortest wavelength?
Green has the shortest wavelength of those.
What has a longer wavelength red or green?
Red light has the longest wavelength that's visible to the eye.Violet light, just past blue in the rainbow, has the shortest wavelengththat's visible to the eye. It's roughly half the size of a wave of red light.
What is the color of the collest star?
The coolest stars are the Brown Dwarfs, so naturally, they're red. ("Red Dwarf" was already taken)
