Question

Match the electromagnetic waves with their typical wavelengths. (a) AM radio waves; (b) Microwaves; (c) Infrared; (d) X-rays. (i) 10⁻¹⁰m; (ii) 10²m; (iii) 10⁻²m; (iv) 10⁻⁴m.

G1 Physics · Accepted Answer

Step 1: Order spectrum by typical wavelength: AM radio waves ~ 10² m; microwave ~ 10⁻² m; infrared ~ 10⁻⁴ m; X-rays ~ 10⁻¹⁰ m. Step 2: Match List I accordingly: (a)→(ii), (b)→(iii), (c)→(iv), (d)→(i). Step 3: This is choice B in the original printed options; the previously imported letter D was incorrect. Final answer: (B) a-ii, b-iii, c-iv, d-i.
