We never learned this!!! I'll give a medal to whoever can help me!!!
I've read and reread my lessons like 7 times it's not there!
The paths of the light waves that interfere to cause firstorder lines
A. differ in length by the wavelength of the light.
B. are parallel lines.
C. are the same length.
D. differ in length by onehalf of the wavelength of the light.

Best ResponseYou've already chosen the best response.1you need to know what causes those bright and dark fringes in interference.. can you tell me why you get interference in the first place?

Best ResponseYou've already chosen the best response.0the interference occurs when waves either cancel each other out or reinforce each other

Best ResponseYou've already chosen the best response.1and when do they reinforce each other? i mean what condition?

Best ResponseYou've already chosen the best response.0Two coherent waves traveling along two different paths to the same point will interfere destructively if there is a difference in distance traveled that is equivalent to a half number of wavelengths. And two coherent waves traveling along two different paths to the same point will interfere constructively if there is a difference in distance traveled that is equivalent to a whole number of wavelengths.

Best ResponseYou've already chosen the best response.0A little pushy aren't we? Okay. Fine. It COULD be C but if they were the same length then they would most likely cancel each other out. (I've learned for several years in a row that usually when something(s) are the same in measurement they tend to cancel each other out.)

Best ResponseYou've already chosen the best response.0So I still wanna stick with A even though I'm still considering C as a small possibility
