Which of the following affects our eye?
Correct answer: E. All of these
- A. Neutrons
- B. Alpha particles
- C. Gamma rays
- D. Laser
- E. All of these
Explanation
The particles with high ionizing capacity will affect the eye tissues. Among the given, alpha particles and gamma rays are highly ionizing radiations, so they are harmful to eyes. However, exposure to neutrons and laser in high intensity can also cause damage to eyes. So, the answer is all of these.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
