Assertion (A): A welder uses mouth mask for protection of eyes.
Reason (R): Welding arc produces X-rays.
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:
Welders use face masks for eye protection from intense UV/Visible/IR radiation and sparks. So (A) is true. Welding arcs primarily emit strong UV radiation, not X-rays, as the main hazard. So (R) is false.
