Grade 12 Physics: Applications of Wave Nature of Light

Stay with one question long enough to think for yourself.

Inside the course

A glimpse of the 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?

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?

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?
