Monochromatic light with a wavelength of 6.4 e -7 meter passes through two narrow slits, producing an interference pattern on a screen 4.0 meters away. the first order bright band lines are 2.0 e -2 meters away from the central bright maxima.
what is the distance between the slits?

The distance between the slits is .

Explanation:

Given that,

The wavelength of the monochromatic light

Distance = 4.0 m

Width

Using formula of the distance between the slits

Where, x = distance from central fringe

D = Distance between the slit and screen

d = distance between the slits

n = number of order

=wavelength

Put the value into the formula

Hence, The distance between the slits is .

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6
