What is the frequency of a red laser beam with a wavelength of 670 nm?

Frequency = (speed) / (wavelength)
Wavelength = 700 nm
For speed of light, use 3 x 108 meters/sec
Frequency = (3 x 108) / (0.7 10-6) = 4.286 x 1014 Hz = 4.286 x 105 GHz

If you have a frequency of 670 what is it wavelength?
Depends on what the speed of the wave is. The wavelength is equal to the speed of the wave divided by its frequency. For light in a vaccum, for instance, the speed is c, or about 3.00 x 10e8 meters/second. If the frequency was in Hertz (cycles/second), then the wavelength would be 448,000 meters. So, this probably is a light frequency. If it were the sound at sea level, the speed is 340 meters/second, so the resulting wavelength would be 0.507 meters. The sound would be nearly an "E".
How will you measure the thickness of human hair?
If you get a normal red laser pointer, you can pretty easily measure it at home. The wavelength of a red laser pointer is typically around 670 nanometers, the one you select may state differently; make note of it. Take one of your hairs and suspend it in front of the laser somehow, but make sure its exactly 1 meter from a flat surface. When you turn on the laser, you should see a dashed line pattern on the board. Measure the distance from the center bright spot to the farthest bright spot you can see and count how many this is. The thickness of your hair is (laser wavelength)*(distance to flat surface)/(distance to bright spot). Then multiply this number by the number of bright spots you counted. So, lets say i could count up to 4 bright spots before it got too dim; i measure the distance from the center to this one to be 5 cm; laser is 670nm and my flat surface is 1 meter away. My thickness is (670*10^-9)*(1)*4/ (.05) = 54*10^-6 meters = 54 micrometers
What is the wavelength of blue light if it has a frequency of 6.67 x 1014 sec Hz?
Blue light has a wavelength of 450-495 nm (nanometers or billionths of a meter). It falls in the higher frequency of the visible light spectrum.Red has the longest wavelength (620-750 nm) and violet has the smallest wavelength in the visible spectrum. The human eye can perceive wavelengths ranging between 380 (violet) and 750 nm (red). Blue has the second shortest wavelength after violet.These are the wavelength ranges for each of the seven colors that comprise the visible spectrum:(Color) (Wavelength)violet 380-450 nmblue 450-495 nmgreen 495-570 nmyellow 570-590 nmorange 590-620 nmred 620-750 nm
