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

The h in E = hf represents:

2 / 10

The wavelength of the electrons can be measured by diffraction. An electron gun accelerates electrons into a beam, these were diffracted and upon diffraction the wavelength was found to be 1.23×10-9m. Calculate the potential difference used to accelerate the electrons from rest into a beam.

3 / 10

BBC Radio Sheffield West Midlands broadcasts on 97.4 MHz. Calculate the wavelength of the radio waves.

4 / 10

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

5 / 10

Which type(s) of images do concave lenses form?

6 / 10

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

7 / 10

The image above shows two wave fronts before, during and after meeting. What is this an example of?

8 / 10

When two polarised filters have an angle of 45° between their two transmission axes, what is the intensity of the light detected compared to the unpolarised incident light?

9 / 10

Calculate the frequency of a wave travelling at 500 ms-1 with a wavelength of 25 m.

10 / 10

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