In the diffraction lab, we will use a laser which has wavelengthis 650 nm and aim it at the hair until a clear diffraction patternis visible on the screen or wall.
1. Does fine or coarse hair result in a greater distancebetween fringes in the resultant diffraction pattern?Explain the reasoning for your response.
2. Explain why laser light is used for this labactivity.
3. Differentiate between interference and diffractionand provide a common example of each from your home, work, orschool experiences.
