Effect of Replacing Red Light with Blue Light on Diffraction Pattern

No Change Takes Place:
- When red light is replaced by blue light, there will be a noticeable difference in the diffraction pattern observed.

Diffraction Bands Become Narrower:
- Blue light has a shorter wavelength compared to red light.
- Shorter wavelengths lead to greater diffraction angles.
- As a result, the diffraction bands will become narrower when blue light is used instead of red light.

Diffraction Bands Become Broader:
- Blue light has a shorter wavelength compared to red light.
- Shorter wavelengths lead to greater diffraction angles.
- This can cause the diffraction bands to become broader due to increased interference patterns.

Diffraction Pattern Disappears:
- In some cases, if the wavelength of the blue light is significantly different from the red light, the diffraction pattern may disappear altogether.
- This is because the change in wavelength can affect the interference patterns and result in the disappearance of the diffraction pattern.

In conclusion, replacing red light with blue light can have a significant impact on the diffraction pattern observed. The outcome can vary depending on the specific characteristics of the light wavelengths involved.
