How do violet light rays differ from red light rays?
Violet light rays have shorter wavelengths and higher energy than red light rays. This difference in wavelength is what gives violet light its characteristic color, which is distinct from the longer wavelength red light.
What happens to the energy of photons if the wavelength of light is doubled?
When the wavelength of light is doubled, the energy of photons decreases by half.
What is the value of the half-power frequency in the given circuit?
The value of the half-power frequency in the circuit is the frequency at which the power is half of its maximum value.
Doubling the amplitude of wave cause its energy to?
The energy of a photon is directly proportional to its frequency. (The proportionality constant is Planck's Konstant.) If one photon has double the wavelength of another, then its frequency is 1/2 the frequency of the other one, and its energy is also half.
How do you double the wavelength of a wave?
To double the wavelength of a wave, you need to decrease its frequency by half. Wavelength and frequency are inversely proportional - as wavelength increases, frequency decreases, so doubling the wavelength requires halving the frequency. This change in wavelength can affect the characteristics of the wave, such as its speed and energy.
What color from blue yellow red or green has the highest energy?
The visible light with the highest frequency (shortest wavelength) carries the most energy. That means it is the light at the violet end of the 'rainbow'. Since the wavelength of violet light is very roughly half the wavelength of red light, a beam of violet light carries roughly double the energy of a beam of red light with equal intensity. In the particle world, a violet photon has double the energy (and double the momentum) of a red photon. We know from (E=H times nu) that energy is directly proportional to the frequency.
Why frequency of light never change when light changes medium?
When light enters another medium it changes speed, but thewavelength changes correspondingly so that the frequency does not change. For example, if light enters a medium where its speed is cut in half, then the wavelength will also be reduced by half.

If a wave is travelling at a certain speed and its frequency is cut in half what would happen to the wavelength of the wave?
it would become longer
If a wave is moving at a constant speed and the wavelength is doubled what will happen to the frequency?
IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).
Why is it better to use energy efficient light bulbs?
Energy efficient light bulb saves half of energy consumed by a regular bulb, although it has a lower range light compare to the high energy consumer bulbs.
What is the lowest ripple frequency of half wave rectifier?
The ripple frequency of a half-wave rectifier is the same as the input frequency.

Photons of light?
... have roughly double the energy of photons of red light, because their frequency is roughly double the frequency of red-light photons. (That also means that their wavelength is roughly half the wavelength of red-light photons, but this fact doesn't help the current discussion at all.)
