Question
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? (1 point)
The image will be the same size and shape.
The image will be similar in shape but spread out more.
The image will be the same shape but much brighter.
The image will be similar in shape but spread out less.

When you replace the green laser with a red laser and observe the diffraction pattern formed through a narrow slit, the key factor to consider is the wavelength of the light.
Green light has a shorter wavelength than red light, meaning that red light will create a diffraction pattern that is more spread out. This is a result of the relationship between wavelength and diffraction; longer wavelengths result in greater diffraction and a wider spread of the pattern.
Therefore, the correct comparison between the two images is:
**The image will be similar in shape but spread out more.**
