Can you find the mistake?

HAHAH they said 650 nm!! its around 532 correct?

 

[Xplorer877]

You got it. Lol! ;D

 

[maxkillz]

lol yea ;D

What do i Win??? J/K no really what do i win

There's actually another mistake, on the second link, frequency should be changed to wavelength.

Any special reason it has to be a green laser?
Wouldn't a simple red laser work the same way?

Green is more visible at lower powers. If you use red you will have to be in a completely dark room. Use any more than 20mW and you will likely fry the organisms. lol!

There is an RPL 473nm 200mW laser waiting for you on the moon. Go get it!!! ;D

Awesome! Has anybody else tried this? :-?

I believe the words are both universal.

no they are two different things, but they are related.

Frequency has an inverse relationship to the concept of wavelength, simply, frequency is inversely proportional to wavelength [ch955] (lambda). The frequency f is equal to the phase speed v of the wave divided by the wavelength [ch955] of the wave:

for light v would be the speed of light. ie~ 3x10^8 m/s

A green laser has a wavelength of 532nm and a frequency of 563Mhz
