Question

Calculate the wavelength of an electromagnetic wave of frequency 100 Hz in vacuum.

G1 Physics · Accepted Answer

Step 1: For radiation travelling in vacuum, wave speed c = fλ. Step 2: Given f = 100 Hz and c = 3 × 10⁸ m/s, λ = c/f. Step 3: λ = (3 × 10⁸)/100 = 3 × 10⁶ m. Final B. Final answer: (B) 3x 10°m.
