What are the differences between an LED and a laser diode?

What is the difference between Lasers and LED's (light emitting diodes)?   Lasers are monochromatic (single color wavelength), collimated (non-divergent) and coherent (wav (MORE)

Can you put a LED inside a laser housing to focus it into a beam just like a laser diode would?

No. Unless the LED is specifically a laser, you can not make it focus like a laser by putting it in a housing.   A laser produces coherent light, which is why it acts like (MORE)

What is required to turn a LED into a laser diode?

you can't. they are two different things. however you might be able to focus it to a small point with a lens. It is possible to use an array of hundreds or thousands of hig (MORE)

What is the answer to 20c plus 5 equals 5c plus 65?

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4
