Two lasers-creates a diffraction pattern on the screen

Reference no: EM13661033

Two lasers, one red (with wavelength 633.0 nm) and the other green (by wavelength 532.0 nm), are mounted behind a 0.150-mmslit. On the other side of the slit is a white screen. When the red laser is turned on, it creates a diffraction pattern on the screen.

Part A

The distance y3, red from the center of the pattern to the location of the third diffraction minimum of the red laser is 4.05 cm. How far L is the screen from the slit? L =______ m

Part B

With both lasers turned on, the screen shows two overlapping diffraction patterns. The central maxima of the two patterns are at the similar position. What is the distance Δy among the third minimum in the diffraction pattern of the red laser (from Part A) and the nearest minimum in the diffraction pattern of the green laser? Δy=______ cm
