Don’t take these facts lightly...
Yes, the headline’s an attempted pun at our favourite topic: Light. With the Mangalyaan doing rounds of Mars, we sense an attitude to learn in the online space. So here we go with our fun facts about light.
1. LIGHT AND THE FLASH ARE RELATED
Light takes 1.255 seconds to get from the Earth to the Moon. That’s faster than, well everything. The only thing/person/character that can stand a chance to compete with that is Flash... or, can he?
2. LIGHT AS A MEASURING TAPE?
Distances in space are so vast that the fastest thing in the Universe – Light – is used to measure them. Now imagine someone running light to measure the distance between 2 planets.
3. Good looking... And then they talk
Age old joke, “Why do people appear intelligent until they start speaking?, Because light travels faster than sound...”. And that’s probably also the reason why you see lightning before you hear the thunder. Probably... no... that is the reason why.
4. You have 8 minutes to get up
Between the sun deciding to shine on you and you deciding to wake, you have exactly 8 minutes and 32 seconds. That’s the time that the sun rays take to reach the earth
5. Around in the world in just one name
By the time you take your name, light can travel around the world more than 4 times. Ever wondered about this before introducing yourself to someone?
