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

Which one of the following types of wave can't be polarised?

2 / 10

Remember Young's slits from GCSE? He's back! Incident monochromatic light of 0.43 μm is shone on a double slit of separation of 0.26 mm. If the screen is 42 cm away from the grating, calculate the fringe width.

3 / 10

A diffraction grating has 350 slits per metre, what the slit spacing, d?

4 / 10

What is the name of distance between the lens and the principal focus?

5 / 10

Calculate the critical angle for the boundary when light leaves a medium of refractive index 1.52 and enters air.

6 / 10

Why is cladding is required in fibre optics?

7 / 10

Two points on a wave have a phase difference of 7π radians, are they in phase?

8 / 10

Two coherent, in phase waves have a path difference of 3λ. What kind of interference occurs?

9 / 10

Calculate the speed of a wave with a frequency of 10 kHz and a wavelength of 2 m.

10 / 10
