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.)
How do violet light rays differ from red light rays?
They have roughly half the wavelength / twice the frequency.
What is the wavelength of a photon whose energy is twice that of a photon with a 580 nm wavelength?
Twice the energy means twice the frequency, and therefore half the wavelength.
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.
What will happen to the waves frequency if its wavelength is made twice as long?
The product of (wavelength) times (frequency) is always the same number ... the wave's speed. So if one of them doubles, the other one must drop by half.

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.
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.
What is the wavelength of a photon whose energy is twice that of a photon with a 580 nm wavelength?
Twice the energy means twice the frequency, and therefore half the wavelength.
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).
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
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.

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.
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.
What happens to the speed of the waves if the frequency of the wave source is halved?
The wavelength of a wave would double if the frequency was cut in half. Wavelength=c/frequency where c equals the speed of light.
What will happen to the waves frequency if its wavelength is made twice as long?
The product of (wavelength) times (frequency) is always the same number ... the wave's speed. So if one of them doubles, the other one must drop by half.
