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

Fishermen use sonar to detect the depth of fish beneath the boat. On this occasion, the echo returned after 0.83 s. The speed of sonar waves through water is 1500 m s-1. Calculate the depth of the fish.

2 / 10

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

3 / 10

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

4 / 10

A focal point for a concave lens is 150 mm away from the lens. An object is then placed 7.5 cm from the lens. Calculate the distance the image is from the lens.

5 / 10

Select the correct statement.

6 / 10

An image of a perfectly circular object of radius 25.8 cm is projected onto a screen. The object is also perfectly circular and has an area of 16.3 cm. Calculate the magnification on the lens.

7 / 10

In a fibre optic cable the core has a refractive index of 1.52 and it's cladding is 1.34. Calculate the critical angle at the boundary between the core and cladding of the cable.

8 / 10

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

9 / 10

A stationary wave at the first harmonic is created on a 40 cm length of string with mass 1.2 kg. The full length of the string is 65 cm and is under tension of 3 N. Calculate the frequency.
