Lightning radiation astronomy is a lecture from the radiation astronomy department on the origin, constitution and occurrence of lightning.

You are free to take this quiz based on lightning radiation astronomy at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, or in the template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Quiz
{Complete the text: A composite { electron density (i) } spectrum is approximately a { power (i) } law over at least the ≈ 5 decade wavenumber range 10-13 m-1 < wavenumber < 10-8 m-1 and that may extend to { higher (i) } wavenumbers.
 * type="{}"}

{True or False, Like all elementary particles, the electron has a corresponding antiparticle of opposite spin but equal mass and charge (-1). - TRUE + FALSE
 * type=""}

{Complete the text: Blue jets differ from sprites in that they project from the { top (i) } of the cumulonimbus above a { thunderstorm (i) }, typically in a narrow cone, to the lowest levels of the { ionosphere (i) }.

Hypotheses

 * 1) Lightning is an effort by the Earth to balance charges impinging on the ionosphere from the solar wind.
