Which Colour is on the top of Spectrum?

Which Colour is on the top of Spectrum?

If we arrange light in the increasing order of wavelength then the color on top is – Red followed by, orange, yellow, green, blue, indigo and violet. if we arrange light in the increasing order of frequency the the color on top is – Violet followed by indigo, blue, green, yellow, orange and red.

Is a rainbow a reflection or refraction?

Rainbows are the result of the refraction and reflection of light. Both refraction and reflection are phenomena that involve a change in a wave’s direction. A refracted wave may appear “bent”, while a reflected wave might seem to “bounce back” from a surface or other wavefront.

What is a real life application of refraction?

Refraction of light can be seen in many places in our everyday life. It makes objects under a water surface appear closer than they really are. It is what optical lenses are based on, allowing for instruments such as glasses, cameras, binoculars, microscopes, and the human eye.

What is refraction simple explanation?

Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows.

What light can’t we see?

There is a lot of light that we just can’t see – that’s invisible to the naked eye. The wavelengths of light comprise the Electromagnetic Spectrum, ranging from the longest to the shortest: radio waves, microwaves, infrared, visible light, ultraviolet light, X-rays and gamma-rays.

How far can light be seen?

Seeing distances Detecting a candle flame: Researchers believe that without obstructions, a person with healthy but average vision could see a candle flame from as far as 1.6 miles. Without the Earth’s curve and from higher up: You might be able to identify objects from dozens, even hundreds, of miles away.
