Electromagnetic radiations is arrangement of electromagnetic radiations in increasing order of energy or decreasing order of wavelength.
With reference to electromagnetic radiation, energy is mathematically expressed as:
Energy (E) = hc/∧ = hcv
where, ∧ = wavelenght of radiation, v = frequency of radiation.
Answer 1: The order of greatest frequency to lowest frequency on basis of colour is: vibgyor, indigo, blue, green, yellow, orange and red.
Thus, vibgyor has highest frequency and red has lowest frequency.
Answer 2: Types of electromagnetic radiation of basis of frequency (from greatest to lowest) is as follow: Gamma rays, X-rays, Ultra Violet radiations, Visible rays, Infrared waves, Microwaves and Radiowaves.
Here, Radiowaves has lowest frequency and gamma rays has highest frequency.
Answer 3: The order of greatest frequency to lowest wavelength on basis of colour is: red, orange, yellow, green, blue, indigo and vibgyor.
Thus, vibgyor has lowest wavelength and red has highest wavelength.
Answer 4: Types of electromagnetic radiation of basis of frequency (from greatest to lowest) is as follow: Radiowaves, Microwaves, Infrared waves, Visible rays, Ultra Violet radiations, X-rays and Gamma rays.
Here, Radiowaves has highest wavelenght and gamma rays has lowest wavelenght.
