Q1:

Two slits apart are illuminated by light of wavelength 600 nm. What is the highest order fringe in the interference pattern?

Q2:

Light of wavelength 710 nm illuminates a double slit with a slit separation of 0.150 m. Light from the slits is incident on a screen 3.00 m away.

Find the distance on the screen between the central maximum and the third maximum of the diffraction pattern.

Find the distance on the screen between the second maximum and the fourth maximum of the diffraction pattern.

Q3:

Find the wavelength of light that produces fringes 7.50 mm apart on a screen 2.00 m away from two slits separated by 0.120 mm.
