Answer:

Wavelength of light is 600 nm

Step-by-step explanation:

Given

Distance between the first order maximum and the tenth order maximum of a double-slit pattern = 18 mm

Separation between the slits = 0.15 mm

Distance of screen from the slits = 50 cm

Wavelength


= (18*10^(-3) * 0.15 *10^(-3))/(0.50*9) \\= 6 *10^(-7)\\= 600nm
