Question

25. The frequency range of white light in the visible spectrum
O From 20 x 1094 Hz to 15x1094Hz
O From 2.5x1014Hz to 4x1014Hz
O From 7 5x1014 Hz to 4x1014Hz
o From 10-14 Hz to 5x 104 Hz​

Answer 1

Visible light falls in the range of the EM spectrum between infrared (IR) and ultraviolet (UV). It has frequencies of about 4 × 1014 to 8 × 1014 cycles per second, or hertz (Hz) and wavelengths of about 740 nanometers (nm) or 2.9 × 10−5 inches, to 380 nm (1.5 × 10−5 inches).
