Expert Solution & Answer

Answer to Problem 1CQ

Our eyes feel restful to gaze off into the distance when objects are at least 6 m away.

Explanation of Solution

The human eye feel relaxed when the viewing object is at least 6 m away but when we gaze at the nearer objects the lenses of our eyes have to contract due to this there is tension in the muscles of the eyes and our eyes start feeling tired after sometime but when we gaze at distant objects our eye muscles are relaxed and are not in tension.

The human eyes are designed to feel relaxed when the object is at the optical infinity.

Conclusion:

Therefore, our eyes feel restful to gaze off into the distance when objects are at least 6 m away.

Consider a image that is located 30 cm in front of a lens. It forms an upright image 7.5 cm from the lens. Theillumination is so bright that that a faint inverted image, due to reflection off the front of the lens, is observedat 6.0 cm on the incident side of the lens. The lens is then turned around. Then it is observed that the faint,inverted image is now 10 cm on the incident side of the lens.What is the index of refraction of the lens?
