The sun is facing a certain side of the earth
Answer:
Radio waves are used for communications and radar. Microwaves are used to cook your food. Infrared waves are used in remote controls and are emitted from all warm objects, allowing them to be used to create heat-sensitive cameras.
Explanation:
Basically electromagnetic waves can be found in your everyday life.
Answer:
Explanation:
I'm pretty sure the answer would be deductive reasoning. Deductive reasoning relies on making logical premises and basing a conclusion around those premises. It does not rely on making inferences and then assuming those inferences to be true.
Answer:
Modern telescopes are capable of seeing bright galaxies up to about 10000 millions light years away
Explanation:
A telescope is a tool that astronomers use to see faraway objects. Most telescopes work by using curved mirrors to gather and focus light from the night sky. The bigger the mirrors or lenses, the more light the telescope can gather.
Modern telescopes gather information from the electromagnetic spectrum far beyond the range of visible light.
The farthest bright galaxies, that the modern telescope is capable of seeing is 10000 millions light years away.
A light-year is how astronomers measure distance in space.
-Light can travel 300,000 kilometres in one seconds!
Light year is the distance that light travel can travel in one year.
-Light can also travel 9,00,000,000,000 kilometers.
-One light is about 10 trillion km.
-Almost 300 years ago ,a Danish scientist named olaus roemer,was the fist man to estimate the distance light travels in a year -and using that he figure out the approximate speed of light!
