In the diffraction lab, we will use a laser which has wavelength is 650 nm and aim it at the hair until a clear diffraction pattern is visible on the screen or wall.

1. Does fine or coarse hair result in a greater distance between fringes in the resultant diffraction pattern? Explain the reasoning for your response.

2. Explain why laser light is used for this lab activity.

3. Differentiate between interference and diffraction and provide a common example of each from your home, work, or school experiences.
