Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is the condition for constructive interference in Young's experiment?

💡 Hint: Think about how many whole waves fit into the path difference.

Question 2

Easy

Describe what happens to light when it passes through two closely spaced pinholes.

💡 Hint: What do we call the pattern from overlapping waves?

Question 1

What happens in constructive interference?

  • Waves cancel each other
  • Waves reinforce each other
  • Waves change direction

💡 Hint: Think about whether the waves are adding to or canceling each other.

Question 2

True or False: Coherent sources have a variable phase difference.

  • True
  • False

💡 Hint: Recall the definition of coherence.

Challenge Problems

Push your limits with challenges.

Question 1

A monochromatic light source produces interference on a screen 1.2m away from the pinholes. If the distance between the pinholes is 0.4mm and the fifth bright fringe is 3cm from the central maximum, calculate the wavelength.

💡 Hint: Convert units as necessary to ensure consistency.

Question 2

In a set of experiments with red and green lasers producing interference, the red laser (λ=650 nm) shows fringes spaced wider apart compared to the green (λ=532 nm). Explain why.

💡 Hint: Consider how wavelength affects the calculation of fringe positions.
