Question

Are lightwave frequency and lightwave energy properties of light that are important for vision?

Answer 1

Explanation:

• The most important organ in our human system that helps us in the concept of "observe" is the Eye. It is necessary to know the principle behind vision.
• Light plays a very important role in viewing of objects.
• The amount of light entering the eye reaches many parts of the eye in a fraction of second to make us view the object clearly.
• Light waves transmit across the cornea to enter the eye through pupil. The pupil becomes dilated or expanded when the light levels are low to allow more amount of light to enter the eye.
• In contrast, the pupil becomes constrict or smaller when the light levels are high to allow less amount of light that enters the eye.
• Light enters the eye in the form of waves.
• The visible spectrum of light ranges from 380-740nm.
• Light wavelength is associated with perception of color in humans.
• For humans, red is associated with longer wavelength whereas the blue and green are shorter in wavelength.
• Depending upon the light wave frequency and energy the human eye produces the image of the object in the eye and aids in the vision.
