Which is more energetic a red photon or a blue photon?
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
How does the wavelength of infrared compared the wavelength of ultraviolet waves?
Wavelength of infra red would be greater than that of ultra violet waves.
Between green light and red light which has a higher frequency?
Red light has a longer wavelength than blue light, (i.e. greater distance for one oscillation of red light compared to blue light) so there are less oscillations in the same period of time for red light, and thus red light has a lower frequency than blue light. More concisely: Wavelength = Wavespeed / Frequency , where wavespeed is constant So Frequency = Wavespeed / Wavelength Therefore as wavelength increases, frequency decreases. Make sense? Jack
What the difference between red light and blue light?
red has a lower frequency and a longer wavelength than blue
Does red light has a longer wavelength than blue light?
Yes.
Why does blue light scatter more than red light?
blue light has shorter wavelength than the red light.scattering of light is more when wavelength is small.
Why is the sky blue and why are sunsets often red?
red is the farthest of all colors Because the wavelength of red is less than the wavelength of blue. Meaning the red wavelength is shorter than the blue one. The shorter it is the farthest and slowest it reach the earth's atmosphere before it dispersed to sky.

Do blue visible light and red visible light have the same wavelength?
No, blue and red visible light have different wavelengths. if you see the rainbow, blue and red can been seen on separate stripes which means they have different wavelengths.
Why won't a very bright beam of red light impart more energy to an electron than a feeble beam of violet light?
Ok, so this goes back to the inverse relationship between wavelength and frequency ( energy). As wavelength increases , frequency decreases, the relationship between the two is a inverse relationship. the Red light, wavelength of approx. 700 m^-7 , has a greater wavelength then of the blue light, 400m ^-7. This means , due to frequency and wavelength having an inverse relationship, blue light has a greater frequency (energy) than red light. This is why blue light, no matter how dim, will impart more energy to an electron , then a red light would.

Why is frequency of red greater than violet?
The wavelength of violet light is shorter.
Does red light has a longer wavelength than blue light?
Yes.
How does a red shift from a blue shift?
A red shift shows us that a object is moving away, while a blue shift shows us an object is moving toward us. Light that has been 'red shifted' has a longer wavelength when it reaches our eyes/telescopes/etc. than it had when it left the object. Light that has been 'blue shifted' now has a shorter wavelength. The reason stretching the wavelength is known as 'red shifting' is that, in the visible spectrum, red light has the longest wavelength. Blue light has a much shorter wavelength than red so when the wavelength is compressed, we call it blue shifting.
Does blue light have a greater speed than red light?
Blue light is diffracted more than red. The way I remember is by thinking about the waves being closer together in the blue light and knowing that each wave interacts with the whatever is causing the diffraction (grating or object). More waves in a given area means more interaction which means more diffraction.
