What is the symbol for candela?
A candela is the power emitted by a source of light in a set direction with a correction to account for the different sensitivity of the human eye to different wavelengths of light. One candela is defined as the luminous intensity of a light source emitting light in one direction at a frequency of 540 x 1012 hertz and has a radiant intensity in that direction of 1/683 watts per steradian.
How do different colors appear on CD?
When white light shines on the CD, the light is separated into seven colours, so different colours appear on the CD.
What does the metric symbol candela stand for?

How are CD players related to energy and power?
a cd player uses a battery to get power, if the devise does not use a battery some other power source will be provided when you purchase it. centrifugal force is created when the disk in the player spins. light is created when a laser emits a beam of light to read the disk. there really isn't much else to say, cd players are very simple devises.
