Viewing the diffraction pattern
The diffraction pattern can be viewed by putting two razor blades touching each other in front of a filament. If filter for red or blue light are used (for monochromatic source), the fringes can be seen clearly.
- We should not use direct sunlight – it can damage the eye and will not give fringes anyway as the Sun subtends an angle of on the eye.
