You need to divide the speed of light by the wavelength. (To have consistent units, you must first either convert the speed of light to nm/second, or convert the wavelength to meters.)

When a wave is passing through a uniform medium and the frequency of this wave increases it wavelength does what?
The wavelength gets longer.
When there are more waves passing through the reference point in a period of time what will happens to the wavelength of the waves?
That means that the frequency increases. In that case, and assuming the speed of the wave doesn't change, the wavelength gets shorter. The general rule is: frequency x wavelength = speed (of the wave)
When there are more more waves passing through the reference point in a period what happens to the wavelength of the wave?
With the wave speed is constant, and the number of cycles which pass a reference point increases, the frequency must increase. With higher frequency and constant speed, the wavelength decreases.
Is Colour related to frequency or wavelength in passing through a medium?
Both, because frequency and wavelength are locked together. If you know one, then you know the other. Knowing both doesn't give you any more information than knowing only one. In that respect, they're interchangeable.
Is the passing of a wave through an object?
Frequency
What is meant by vacuum wavelength?
Vacuum wavelength is the wavelength that is measured if the wave is passing through a vacuum. To get the wavelength in a medium you need to know the refractive index.
The speed of sound in water is 1430 ms Find the wavelength of a sound with a frequency of 286 Hz traveling through the water?
Formula is velocity=frequency X wavelength so Wavelength = 5m
What is the equation for wavelength?
The formula for wavelength λ = v/f where v is the velocity f is the frequency of the wave and λ (lambda) is the symbol for wavelength Wavelength formulaC=λf or λ=C/f
How does sound travel through solid objects?
Sound is a longitudinal wavelength that has wavelength, velocity, frequency and amplitude. It travels through solid objects by going through vibration.
What is is The number of waves passing a point per second?
frequency
What is the frequency of light passing through a ruby?
That depends entirely upon its frequency before it entered.
What is the wavelength of white?
It does not have a single wavelength; it is a mixture of colors with different wavelengths. For example, if you shine red, green and blue lights of similar saturation strength together (so that one doesn't overpower the others) the result will appear white. There's an old saying that black is the absence of color, while white is the presence of all colors. Which is why another term for visible light is 'white light'.
