The correct answer is option 'D': Both statement 1 and statement 2 are true, and statement 2 is the correct reason for statement 1.
Explanation:
Statement 1: The phenomenon of the persistence of vision is employed in cinematography.
The persistence of vision refers to the optical illusion in which multiple discrete images are perceived as a continuous motion. This phenomenon allows us to perceive motion in movies, animations, and other forms of visual media. In cinematography, a series of individual frames is projected onto a screen at a rapid speed, typically 24 frames per second. Due to the persistence of vision, our eyes retain the image for a short duration, creating the illusion of continuous motion.
Statement 2: The image formed on the retina of an eye persists for 1/16th of a second.
When light enters the eye, it passes through the lens and focuses on the retina at the back of the eye. The retina is a layer of light-sensitive cells that convert the incoming light into electrical signals, which are then transmitted to the brain for interpretation. However, once the light stimulus is removed, the image formed on the retina does not disappear instantly.
The persistence of the image on the retina is due to the afterimage effect. The retina retains the image for a short duration even after the light stimulus is removed. This afterimage duration is approximately 1/16th of a second, during which the image gradually fades away.
Explanation of the Correct Answer:
The correct answer is option 'D' because both statements 1 and 2 are true, and statement 2 provides the correct reason for statement 1.
Statement 1 states that the phenomenon of the persistence of vision is employed in cinematography, which is true. Cinematography relies on the persistence of vision to create the illusion of motion by projecting a series of still frames at a rapid rate.
Statement 2 states that the image formed on the retina of an eye persists for 1/16th of a second, which is also true. The afterimage effect on the retina allows us to retain the image for a short duration, contributing to the persistence of vision.
Furthermore, statement 2 provides the correct reason for statement 1. The persistence of the image on the retina for 1/16th of a second is the underlying mechanism that enables the illusion of motion in cinematography. The rapid projection of individual frames takes advantage of this persistence to create the perception of continuous movement.
Therefore, option 'D' is the correct answer, as both statements are true, and statement 2 is the correct reason for statement 1.
