Why are danger signals always red in color?

  1. Red light is least scattered by fog and smoke

  2. It is the color of danger

  3. Both A and B

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer

  2. Violet

  3. Indigo

  4. White
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Fine particles scatter light of shorter wavelength and larger particles scatter light of longer wavelength. However, if the size of the scattering particles is large enough, then, the scattered light may even appear white.

What are the colours of the Sun observed most during sunrise/sunset and noon? 

  1. white and red

  2. reddish and orange

  3. yellow and reddish

  4. orange and blue
Reveal answer Fill a bubble to check yourself

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A 3 pin plug consists of three pins (hence the name). Each pin must be correctly connected to the three wires in the electrical cable. Each wire has its own specified color so as it can be easily identified.
The LIVE wire is RED OR BROWN. This is connected to a fuse on the live pin. The electric current uses the live wire as its route in.
The NEUTRAL wire is BLUE OR BLACK. This is the route the electric current takes when it exits an appliance; it is for this reason the neutral wire has a voltage close to zero.
The EARTH wire is GREEN OR  YELLOW and connected to the earth pin. This is used when the appliance has a metal casing to take any current away if the live wire comes in contact with the casing.
