The speed of light is a constant, doesn't change for colour. The wavelength changes by colour though. A white light source moving away real fast will become redder (longer waves), while the same source moving towards you will become bluer (shorter wavelength)
You seem to be talking about a light wave. If you increase the amplitude the light gets brighter, and if you decrease it gets dimmer. Amplitude has no effect on colour.

Increase
The cause of grass to increase/ decrease is how much you water it and not water it, how much sun light it gets and air.
pooop hee heee
The decrease of light intensity on an LDR will cause the resistance of the LDR to increase, which will result in a decrease in current flow through the circuit. As a result, the ammeter reading will decrease.
No, the alcohol is what burns so it will decrease.
The pupil
When you decrease the wavelength of a wave, its frequency and energy increase. This is known as blue shift and is common in light waves. Conversely, when you increase the wavelength of a wave, its frequency and energy decrease. This is known as red shift and is also observed in light waves.
blue light is an ELECTROMAGNETIC WAVE.ALL THE EM WAVES HAVE THE VELOCITY 3*10^8M/S IN VACUUM.Hence the blue also..
When light strikes a photocell, the resistance decreases, allowing current to flow more freely.
