Gamma Rays-have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum.
Which electromagnetic wave has minimum wavelength?
Which of the following electromagnetic waves has minimum wavelength and minimum frequency?
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
Which of the following has minimum wavelength?
Out of the given wavelengths gamma rays have the minimum wavelength and infrared rays have the maximum wavelength.
What is the wavelength of electromagnetic?
Visible light has a wavelength range from ~400 nm to ~700 nm. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*1014 Hz.

What are the 7 types of waves?
Though the sciences generally classify EM waves into seven basic types, all are manifestations of the same phenomenon.
- Radio Waves: Instant Communication. …
- Microwaves: Data and Heat. …
- Infrared Waves: Invisible Heat. …
- Visible Light Rays. …
- Ultraviolet Waves: Energetic Light. …
- X-rays: Penetrating Radiation. …
- Gamma Rays: Nuclear Energy.
What is the longest wavelength?
Which is the electromagnetic wave?
An electromagnetic wave can travel through anything – be it air, a solid material or vacuum. It does not need a medium to propagate or travel from one place to another. … This is known as the electromagnetic spectrum. Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, etc.
What is use of infrared?
Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus. Extensive uses for military and civilian applications include target acquisition, surveillance, night vision, homing, and tracking.
What is the same for all electromagnetic waves in a vacuum?
Electromagnetic radiation is a type of energy that is commonly known as light. Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum.
Which Colour has minimum frequency?
red light has maximum wavelength and violet has minimum wavelength.As the frequencyandwavelengthof a wave are inversely proportional to each other so,red lighthas minimum frequency and violet light has maximum frequency. Moreover, violet light has maximum energy andred lighthas minimum energy.
Which is not electromagnetic wave?
Beta rays are not electromagnetic waves because they are charged particles and are capable of getting deflected by the magnetic field. These rays are not pure energy as a photon.
Which wave has maximum penetrating power?
What wavelength is dangerous?
Ultraviolet (UV) (Wavelength 10-7 – 10-8 meters)
UV-C rays are the most harmful and are almost completely absorbed by our atmosphere. UV-B rays are the harmful rays that cause sunburn. Although UV waves are invisible to the human eye, some insects, such as bumblebees, can see them.
What does wavelength mean?
Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. … Wavelength is inversely proportional to frequency. This means the longer the wavelength, lower the frequency. In the same manner, shorter the wavelength, higher will be the frequency.
