Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A laser with a wavelength of 500 nm illuminates a single slit of width 1 mm. Calculate the angle to the first minimum in the diffraction pattern.

💡 Hint: Convert units appropriately and remember that sin(θ) is small for small angles.

Challenge 2 Hard

Describe how diffraction affects sound in a large stadium and how it can influence acoustics.

💡 Hint: Consider how sound travels and interacts with space.
