The correct option is C 4,1,3,2
Radio waves-Visible-Ultraviolet-X-rays is the correct ascending order
for frequencies of the following radiations.
Radio waves - Radio waves are a type of electromagnetic radiation with
wavelengths in the electromagnetic spectrum longer than infrared light. Radio
waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz
(Hz). At 300 GHz, the corresponding wavelength is 1 mm, and at 30 Hz is
10,000 km. Like all other electromagnetic waves, radio waves travel at the
speed of light. They are generated by electric charges undergoing acceleration,
such as time varying electric currents.
Visible - Electromagnetic radiation in this range of
wavelengths is called visible light or simply light. A typical human eye will
respond to wavelengths from about 390 to 700 nanometers. In terms of frequency,
this corresponds to a band in the vicinity of 430–770 THz.
Ultraviolet - Ultraviolet (UV) light falls in the range of the EM
spectrum between visible light and X-rays. It has frequencies of about 8 × 1014
to 3 × 1016 cycles per second, or hertz (Hz), and wavelengths of about 380
nanometers (1.5 × 10−5 inches) to about 10 nm (4 × 10−7 inches).
X-rays - X-rays are electromagnetic waves with wavelengths in the range of
0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz
to 30 exahertz (3×1016 Hz to 3×1019 Hz) and energies in the range 100 eV to 100
keV. ... Microwaves encompass the high frequency portion of the radio section
of the EM spectrum.
