Question 1.
What is diffraction?
Show hintHide hint
Think about what happens to a wave when it hits an edge.
Question 2.
What happens to waves with longer wavelengths?
Show hintHide hint
Consider how wave size and opening size relate.
3Question 3.
What is diffraction?
- A. Bending of light only
- B. Bending of waves
- C. Reflection of waves
Show hintHide hint
Think about how waves interact with obstacles.
4Question 4.
Longer wavelengths diffract more than shorter wavelengths.
- True
- False
Show hintHide hint
Consider how wave size interacts with gaps.
Question 5.
A light source emits waves with a wavelength of 600 nm through a slit that is 0.3 mm wide. Predict how the diffraction pattern would change if the slit width is decreased to 0.1 mm.
Show hintHide hint
Consider how a narrower slit changes the path and behavior of the waves.
Question 6.
Explain why diffraction patterns vary across different wavelengths of light when passed through the same opening.
Show hintHide hint
Think about how wavelength interacts with the physical dimensions of an opening.
