What does the wavelength of visible light waves correspond to?

Answers

The wavelength of the visible range of the electromagnetic spectrum lies between \boxed{400\,{\text{nm}} - 700\,{\text{nm}}} .

Further Explanation:

The Electromagnetic spectrum is the complete range of the electromagnetic radiation which expresses all the radiation starting from the Gamma rays to the radio waves. The electromagnetic spectrum is the detailed spectrum that explains all the electromagnetic radiations.

The electromagnetic radiations are the transverse waves which do not require any medium for their propagation. The electromagnetic waves can easily travel through space. All the electromagnetic radiations travel at the speed of light.

The different radiations in the electromagnetic spectrum are as follows:

  • Gamma rays
  • X-rays
  • Ultraviolet rays
  • Infrared rays
  • Micro waves
  • Radio waves

The wavelength and the frequency ranges for the different electromagnetic radiations is as shown in figure attached.

Therefore, the wavelength of the visible range of the light in the electromagnetic spectrum is \boxed{400\,{\text{nm}} - 700\,{\text{nm}}} .

Answer Details:

Grade: High School

Subject: Physics

Chapter: Electromagnetic Waves

Keywords:

Electromagnetic spectrum, visible light, EM waves, wavelength, 700nm, 400 nm, 7000 A, frequency, gamma rays, transverse waves.

Explanation:

Visible light is a very part of electromagnetic spectrum. We can see the visible region of the electromagnetic spectrum.

The frequency and the wavelength has an inverse relationship.

For example, the red light has large wavelength and low frequency. Violet has a short wavelength and higher frequency.

The frequency range of visible region is from 400 nm to 700 nm.

When discussing discordant and harmonious sound waves, which statement is false? A. Both types of waves are the result of component waves with different frequencies. B. Knowing the frequencies of the original waves is useful in determining if the result will be discordant or harmonious. C. Low ratios of the frequencies of the original and resultant waves indicate discordant waves. D. If the original waves combine to form irregular displacements of air, the sound will be discordant.

Answers

Correct answer choice is :


C) Low ratios of the frequencies of the original and resultant waves indicate discordant waves.


Explanation:


The sound is created when something vibrates. The vibrating body makes the means around it to vibrate. Vibrations in the air are described going longitudinal waves, which we can hear. Sound waves consist of regions of high and low pressure named compressions and rarefactions. The left ventricle will ultimately lose as depolarization opens from the right ventricle, but the stay in conduction effects in a wide QRS system. In the appearance of LBBB, the T wave should be discordant or diverted opposite the final deflection of the QRS system.
