Light of wavelength 675 nm passes
through a double slit, and makes its
first minimum (m = 1) at an angle of
0.111 deg. What is the separation of
the slits, d, IN MILLIMETERS?
(Remember, milli means 10-3.)
(Unit = mm)

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up

What would occur if the index of refraction of a material was less than n=1? the speed of light would increase to a speed larger than the maximum speed of light in a vacuum. the light wave would not bend at all though the material. the light wave would not be able to refract and would instead reflect off of the material. the speed of light would reduce to values close to 0 m/s.

Two lasers are shining on a double slit, with slit separation d. laser 1 has a wavelength of d/20, whereas laser 2 has a wavelength of d/15. the lasers produce separate interference patterns on a screen a distance 5.30 m away from the slits. part a which laser has its first maximum closer to the central maximum? view available hint(s) which laser has its first maximum closer to the central maximum? laser 1 laser 2
