Waves & the Nature of Light Random Retrieval

This quiz contains all the questions in the Waves & the Nature of Light section. The website will pick 10 questions at random.

1 / 10

A blue laser of wavelength 480 nm is incident on a diffraction grating of 3.00x106 lines per metre, how many order maxima (excluding 0 order) can be seen?

2 / 10

Reducing the width of a single slit that has monochromatic light passing through affects the central maximum, how?

3 / 10

An inverted image is seen 3 times its original size when the object is placed 140 mm front of a convex lens. Calculate the focal length of the lens.

4 / 10

The speed of light in the core of a fibre optic cable is 2.04x108 ms-1. Calculate the refractive index.

5 / 10

Light passes from air through a glass container and into olive oil. Select the diagram that best shows this. Refractive indexes are as follows: glass = 1.52 and oil = 1.47

6 / 10

This diagram shows a ray of light travelling through a semi-circular glass block. Which letter would represent the critical angle if TIR occurred?

7 / 10

The refractive index of glass is 1.52, what speed does light travel through it?

8 / 10

Why is cladding is required in fibre optics?

9 / 10

Soumya plays a note of wavelength 25 cm on her synthesiser. She knows the speed of sound is 340 ms-1 in air. Calculate the frequency.

10 / 10
