Question

investigating with data: exoplanets: is there life out there? 5. compare your observations from question 4 to your prediction in question 1. what was different or surprised you? 6. repeat the investigation with red light and purple light. 7. how did red and purple light behave the same when passing through the slit? 8. how did red and purple light behave differently when passing through the slit?

Explanation:

Step1: Analyze light - behavior basics

Both red and purple light are forms of electromagnetic radiation and will exhibit wave - like behavior when passing through a slit.

Step2: Identify common wave - like behavior

Both will diffract, which means they will bend around the edges of the slit and spread out to form an interference pattern on a screen behind the slit. This is due to the wave nature of light.

Step3: Consider differences based on wavelength

Red light has a longer wavelength than purple light. The angle of diffraction $\theta$ is related to the wavelength $\lambda$ by the formula $d\sin\theta = n\lambda$ (where $d$ is the slit width and $n$ is an integer). So, for the same slit width, purple light (with shorter wavelength) will have a smaller angle of diffraction and a more closely spaced interference pattern compared to red light.

Answer:

1. Both red and purple light diffract (bend around the edges of the slit) and form an interference pattern when passing through the slit.
2. Red light, with its longer wavelength, has a larger angle of diffraction and a more spread - out interference pattern compared to purple light which has a shorter wavelength and a more closely spaced interference pattern.
