The wavelengths of which electromagnetic waves is between those of radio waves and infra-red waves? Correct Answer Microwaves

CONCEPT:

  • Electromagnetic spectrum: It is a collection of a range of different waves in sequential order from radio to gamma electromagnetic waves.

Frequency (ν) = speed of light (c)/wavelength (λ)

  • Radio waves: The lowest frequency portion comes in radio waves generally, has wavelengths range between 1 mm to 100 km or frequencies between 300 GHz to 3 kHz.
    • There are several subcategories in between these waves like AM and FM radio.
  • Ultraviolet wave: The wave having a frequency less than X-rays and more than visible light is called the Ultraviolet wave. It is dangerous for our skin.
  • Visible Light: A portion in the spectrum of electromagnetic waves that is visible to the human eye is called visible light.
  • Microwaves: The part of the electromagnetic spectrum having the frequency more than that of radio waves and less than that of infrared waves are called microwaves.

Explanation:

From the above explanation, we can see that ultraviolet, X-ray, gamma-ray & Microwaves are all electromagnetic wave

And among all these microwaves are the one which lies between infrared and radio wave spectrum

Hence option 4 is correct among all.

The moon looks blood red during a total lunar eclipse because some of the sunlight passes through Earth’s atmosphere to reach the moon. As the white light breaks up while passing through the atmosphere, most of its blue-colored wavelengths are absorbed and scattered. The remaining red wavelengths light up the moon in blood-red color. Which of the following statements do not support the assertion of the above-given statement? I: The moon looks blood red during a total lunar eclipse as the white light breaks up due to the Earth's atmosphere where most of its red-colored wavelengths are absorbed. II: The moon looks blood red during a total lunar eclipse as the earth blocks the white light to travel to the moon.
