To determine:
The stimulus for vision from following forms of energy:
(a) Chemical
(b) Electrical
(c) Mechanical
(d) Radiant
Answer to Problem 1RQ
Solution:
(c) Radiant: Vision is found operable only in the presence of light and light is classified as a form of radiant energy. The radiant energy can be defined as the energy of the gravitational radiation and
Explanation of Solution
The radiant energy is usually used in the lighting, heating, solar energy, and radiometry. The radiant energy travels in the form of waves. The lengths of these waves are different and the spectrum of these waves is known as the electromagnetic spectrum. The radiant energy includes infrared waves, ultraviolet waves, X-rays, visible light, and radio waves. The light energy stimulates the eyes and plays a significant role in vision.
