MUSCLE PHYSIOLOGY

Detailed explanation-1: -The given statement is False. We can see an object because light, on getting reflected from the object, is scattered and diffused.

Detailed explanation-2: -All electromagnetic radiation is light, but we can only see a small portion of this radiation-the portion we call visible light. Cone-shaped cells in our eyes act as receivers tuned to the wavelengths in this narrow band of the spectrum.

Detailed explanation-3: -In short-light itself is not visible, but it allows us to see because our eyes are sensitive to light and our brains process the light signals that went into our eyes. So light hits an object and is reflected back into our eyes, and that allows us to see the object.

Detailed explanation-4: -Visibility of an object depends on the ray reaching our eyes after reflection from the object’s surface. Thus, we can see objects only in the presence of light.
