NEET Physics Question - Ray Optics - Total Internal Reflection

Assertion (A): In medical technology endoscopy, optical fibres are used to facilitate visual examination of internal organs of the body.

Reason (R): Optical fibres are fabricated so that there should be very less absorption of light and hence no appreciable loss of light intensity.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Optical fibers are indeed used in endoscopy to transmit light for internal examination. This is possible because they are designed for very low light absorption, ensuring minimal loss of light intensity over their length. Both statements are true and R explains A.
