10 Interesting Light Facts
Let’s find out light facts if you want to enjoy the amazing trivia about optics, sunlight, color and speed of light. The life of human being is also dependent on light. Without sunlight, people can do nothing in this world. Here are the facts about light for you:
Light Facts 1: electromagnetic radiation
Electromagnetic radiation is called as a light if you see the definition based on the physics. However, the light that we see in our daily life is considered as a part of the electromagnetic spectrum which can be seen by human eyes. This light is called as the visible spectrum.
Light Facts 2: UV light
It is not easy for human being to see the UV or Ultraviolet light if they do not use a special tool. There are some animals in the world which can see the parts of light which cannot be received by humans eyes. For instance, the UV light can be seen by some insects.
Light Facts 3: infrared light
Another type of light which cannot be seen by human eyes is the wavelength of the infrared light. If due to the fact that infrared light is too long to see.
Light Facts 4: UV light
Do you know the function of UV light to the life of human being? Many forensic scientists utilize the UV light to show the people the things that they cannot see using the eyes.
Light Facts 5: optics
Optics is a branch of physics which studies the behavior and properties of light. Check light bulb facts here.
Light Facts 6: Isaac Newton
Isaac Newton is the scientist who made an observation about colors of light. His research involves a glass prism which is hit by a thin beam of sunlight. The angle of the glass prism produces some visible colors such as red, orange, yellow, green, blue, indigo and violet. People call it ROYGBIV.
Light Facts 7: Light travels
You should never be surprised to find out that light can travel very fast. The speed of light in an empty matter can travel 300,000 km per second or 186,000 miles per second.
Light Facts 8: travel of light
The fastest speed of light is in vacuum area. If the light travels in air, water and glass area, it is usually slower.
Light Facts 9: light from earth to moon
Can you guess the traveling time of light from earth to reach the moon? It only needs 1,255 seconds.
Light Facts 10: ocean
Sunlight is the primary source of light to human’s life. It can break the ocean at the depth of 262 feet or 80 m.
Plants need sunlight when they want to make food and produce oxygen. The process is called photosynthetic. Are you interested with facts about light?
