Answer:
Defination
Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes.
Uses of light energy
Light energy is a form of electromagnetic radiation that can be seen by the human eye. But there are also many commercial and scientific uses of light energy and some of them are listed below.
Food
Light is the only source of food generation for all living organisms. Every organism is dependent on light for their energy and food except a few chemotrophic organisms such as bacteria.
Vision
Any organism is able to view the objects around them due to the presence of eyes. But these might be useless without light. The eyes receive the image when light falls on it and the information is sent to the brain. Hence, light let us see objects around us.
Colours
The whole world is beautiful due to colours and all these colours are possible due to light. The light consists of many spectra and every spectrum has an individual colour which is broadly specified as VIBGYOR.
A plane mirror makes an image of objects in front of the mirror; these images appear to be behind the plane in which the mirror lies. ... Plane mirrors are the only type of mirror for which a real object always produces an image that is virtual, erect and of the same size as the object.
