It can determine a lot of different things. You can determine the wavelength of the light wave from the frequency and the speed: wavelength = (speed)/(frequency). Speed of light is approximately 3 x 108 m/s.
The energy of the photons can be determined by the frequency:
Energy of a photon = h * frequency; h is Planck's constant = 6.626 x 10-34 Joule*sec. Higher frequency waves are sometimes called high-energy waves (X-rays, gamma rays for example)
Different frequencies of visible light will be different colors. Red has the lowest frequency of the visible spectrum, and violet is the highest frequency. Note that each color is not a specific frequency, but a range of frequencies, with the color shifting as frequency gradually changes.
Red: 400 to 484 THz (TeraHertz or 1012 Hertz)
Orange: 484 to 508 THz
Yellow: 508 to 526 THz
Green: 526 to 606 THz
Cyan: 606 to 630 THz
Blue: 631 to 668 THz
Violet: 668 to 789 THz

Its wavelength (or frequency).
Yes. c=fL where L = wavelength, c=speed of light and f = frequency (I cannot write the Greek letter lamda for wavelength)
The frequency of a sound wave will determine the pitch (or note).
Frequency controls the color of the light.
I assume you are asking in regard to the photoelectric effect. The intensity of the photons can be viewed as the brightness of the light. However, the frequency is the number of wavelengths that pass a certain point in a second. The frequency is also used to determine the energy of the photon (E=hf).
Frequency can be found in sound, light, and line current. An example of frequency is, the frequency wave of light will determine what color the light is.
Its wavelength (or frequency).
Energy/frequency or energy*wavelength/speed of light.
Frequency or wave length.The relation between frequency f and wave length lof a light waveis given by; f = c/l, where c is light's speed.
to find the frequency of a light wave you need to know its wavelength. The frequency is equal to the speed of light (3x10^8 m/s) divided by the wavelength in metres. Alternatively, if you were given the energy of each photon of light in joules you could just divide the energy by plancks constant (6.63x10^-34) to leave you with the frequency in Hz.

Astronomers determine whether a star is moving toward or away from the Earth via the Doppler effect. Imagine a motorcycle moving past you. As it drives towards you, it has a higher frequency, and a lower frequency when it drives away. The same thing happens with light. As an object moves towards us, its light has a higher frequency and lower wavelength - this is called blueshift. As an object moves away from us, its light has a lower frequency and higher wavelength - this is called redshift.
