The easiest way would be to find a descriptive article on the internet that shows
the visible colors spread out with some wavelengths labeled. There, you can find
the approximate wavelengths for light of various colors.
If you don't know the color of the light, then in order to find its wavelength,
you'd need to know either its frequency or the energy of a photon (quantum).
Energy of a photon = h f
h = Planck's Konstant = about 6.63 x 10-34 joule-second
f = frequency of the light wave or photon
But the frequency is (speed of light)/(wavelength)
so, Energy = h c/wavelength .
If you know either the energy of the photon or its frequency, you can use
this stuff to find its wavelength.
In this discussion, I've toggled back and forth a few times between the frequency/wavelength
of the quantum and the frequency/wavelength of the light wave. Don't worry. They're
the same.

What affects the wavelength of a mechanical wave moving trough a medium?
The amount of initial energy affects the wavelength of a mechanical wave moving through a medium. A mechanical wave requires an initial energy input to be created. Once this initial energy is added, the wave will travel through the medium until all the energy has been transferred.
How do you know that light is a form of energy?
If the light has sufficiently high frequency (short wavelength), then it can dislodge electrons from the surface of material upon which it shines, and cause an electric current in the material. (The effect doesn't depend on how bright the light is, only on its wavelength. Explaining this strange effect won Dr. Einstein his first Nobel Prize.) Nowadays, materials and structures have been developed in which this effect is produced by light of relatively longer wavelength (lower energy). They're used in the photocells that may power your wristwatch and your calculator, and in large assemblies, deliver useful quantities of clean, renewable electric energy.
What is the initial velocity that must be given to a 1kg mass if it is to move to a height of 20m. what is the total energy?
After 20 m all kinetic energy have been transformed to potential energy.Epot=m*g*h=0.15*9.81*20=29.4 Joule
How does the wavelength of waves used in the microwave ovens compare with the wavelength of waves used for radar?
The wavelength used in the microwave oven is about 12 centimeters. (rounded) In the early days, there were radar systems that used wavelengths longer than that, but there haven't been any for several decades now.
A system absorbs 640J heat and does work of 260J the change in internal energy of the system will be?
the system has been given internal energy of 640j and the work system does on surroundings is 260j. therefore by first law of thermodynamics the internal energy of system increases by (640-260=380)j.

How to find potential energy when only mass and velocity time is given?
To get the potential energy when only the mass and velocity time has been given, simply multiply mass and the velocity time given.
What affects the wavelength of a mechanical wave moving trough a medium?
The amount of initial energy affects the wavelength of a mechanical wave moving through a medium. A mechanical wave requires an initial energy input to be created. Once this initial energy is added, the wave will travel through the medium until all the energy has been transferred.
