What are the lengths of light waves?
The visible spectrum of the electromagnetic spectrum (visible light) goes from about 380nm to 750nm. Violet is 380nm or so ranging all the way to red which is 620nm to 700nm or so.
What does frequency control in light?
Frequency controls the color of the light.
Which has a lower frequency yellow light or blue light?
Yellow light has the lower frequency.
When the frequency of light matches the natural frequency of molecules in a material light is?
Light is absorbed by the molecule.
What is the light frequency?
The frequency of a wave of light is given by speed of light/wavelength, or by energy/Planck's constant.If you know the frequency or the energy associated with the light, it is easily calculated.

How fast does light really travel?
it can travel from 380nm [nanometres] to 740nm
Using standard values for the speed of light if you convert 380nm UV light to an audio frequency equivalent in the octave below middle C what is the frequency to one decimal place?
The constraints you place on the solution are confusing ... there seems to betoo many qualifications.The octave below middle-C covers the range of audio frequencies of 128 - 256 Hz.Careful measurement reveals the frequency of 380-nm light to be somewhathigher than that.Frequency = speed/wavelengthUsing the typical rounded value for the speed of light,Frequency = 300,000,000/380 x 10-9 = 7.895 x 1014 Hz(789,473.68 GHz, rounded)
What is an example of frequency?
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.
What color will a red object appear if only Red light is shone on it?
It will appear somewhat Orange. This is due to the roughly 650nM wavelength from the red light and the reflection of the yellow at around 380nM.
What does frequency control in light?
Frequency controls the color of the light.
What is the optimum wavelength of light absorbed by chlorophyll and why?
The optimum wavelength of chlorophyll is 430nm (in a light spectrum of 380nm-750nm going in 10 incements) We did a lab and it required us to determine the optimum wavelength of chlorophyll by testing the absorbance of light in 10nm increments from 380nm-750nm. Optimum wavelength is the wavelength of light that is absorbed best by a substance. So when we tested all the wavelngths 380-750 in 10 increments (380,390,400,410,420....) 430 had the highest absorbance. we used a Spec 20 machine to find the absorbance.
Which has a lower frequency yellow light or blue light?
Yellow light has the lower frequency.
When the frequency of light matches the natural frequency of molecules in a material light is?
Light is absorbed by the molecule.
What is the light frequency?
The frequency of a wave of light is given by speed of light/wavelength, or by energy/Planck's constant.If you know the frequency or the energy associated with the light, it is easily calculated.
What determine the color of a light wave?
Its wavelength (or frequency).
What is the formula for converting frequency of light into wavelength?
wavelength = c/frequency of light where c is the speed of light.
