1. What phenomenon is shown in the image? Single-slit diffraction

Question

2. Which of the following describes the limit on using waves to image an object? The object must be much larger than the wavelength used.

3. When water waves diffract through a narrow slit, the slit is “narrow” relative to what? The wavelength of the waves

4. Green light has a shorter wavelength and a higher frequency than red light. Suppose a green laser is directed through a narrow slit, forming a diffraction pattern. You record the image and then replace the laser with a red laser. How will the second image compare to the first? The image will be similar in shape but spread out more.

5. When describing water waves passing around an obstacle in a ripple tank, what is meant by the obstacle’s “shadow”? The area directly behind the object where diffracting waves have not yet reformed the wavefronts

I took the quick check

Answer 1

Great job! It looks like you have a good understanding of the concepts related to diffraction. Let me know if you have any other questions or if there's anything else I can help you with.
