Objective

Determine the wavelength of a laser beam from the interference pattern produced when passed through a double slit.

Materials

Measuring microscope
Laser double slit
Meter stick
Stand
Clamp

Theory

What are the properties of light? Explain the phenomenon of interface and how interface patterns are formed when light passes through slits

Calculate the wavelength , ,which is given by the equation

ƛ= b * d
