(i) Optical fibers are widely used in endoscopic procedures for medical imaging
(ii) They are utilized in laser surgery for delivering laser light precisely to target tissue
(iii) Optical fibers play a key role in various diagnostic imaging techniques such as Optical Coherence Tomography (OCT).


(6b)
(i) Optical fibers are extensively used in military communication systems.
(ii) They serve as the backbone for various fiber optic sensor systems used in defense applications.
(iii) They are employed in the development of underwater surveillance systems

(7a)
A perfect blackbody is an idealized object that absorbs all incident electromagnetic radiation, regardless of wavelength or angle, and emits radiation.

(7b)
(PICK ANY TWO)
(i) As temperature increases, the peak wavelength of emission decreases.
(ii) The intensity of radiation increases with temperature, with a higher temperature blackbody emitting more radiation at all wavelengths.
(iii) The graph shows a continuous spectrum, indicating that the blackbody emits radiation at all wavelengths.
(iv) At lower temperatures, the intensity is concentrated in longer wavelengths, while at higher temperatures, it extends to shorter wavelengths.
