Grade 12 Physics: Applications of Wave Nature of Light

One question a day, with solutions and a Socratic tutor.

Sample questions

Question 01

A light wave travels in a medium with a low index of refraction and reflects off a medium with a higher index of refraction. What phase change does the reflected wave undergo? Open question

Question 02

Monochromatic light with a wavelength of \( \lambda \) strikes a soap bubble at normal incidence and interferes constructively. Which of the following are possible thicknesses for the bubble? Open question

Question 03

In a certain thin film, the wavelength of light is 70% of its wavelength in a vacuum. What is the index of refraction of the film? Open question
