Question

What will the interference pattern between the two above waves produce? A wave similar to the top but with double the amplitude A wave similar to the top but with half the amplitude A wave similar to the bottom but with double the amplitude A wave similar to the bottom but with half the amplitude A flat line A laser beam with a wavelength of 500 nm is passed through a single slit with a width of 0.1 mm. Find the distance (in cm) between the central maximum and the first minimum of the diffraction pattern on a screen 5 m away?

Explanation / Answer

Question.3.

Answer :   A flat line.

Question 4.

Wavelength of beam = 500 nm

Single slit

     width d = 0.1    mm

Distance of screen D = 5 m

Distance between central maxima and first minima = X

then       X / 5 = wavelength / d

or        X    = 5*(500*10-9) / (0.1*10-3 )   = 0.025 m = 2.5   cm
