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 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 a electromagnetic wave?
Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. Visible light has a wavelength range from ~400 nm to ~700 nm. … Electromagnetic waves with shorter wavelengths and higher frequencies include ultraviolet light, X-rays, and gamma rays.
What size wavelengths do harmful types of electromagnetic waves typically have?
Find out more in our main article on X rays. Typical size: 0.1 nanometers (the width of an atom). Gamma rays: These are the most energetic and dangerous form of electromagnetic waves. Gamma rays are a type of harmful radiation.
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 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 minimum frequency?
Which color has longest wavelength?
How do you find a wavelength?
Wavelength can be calculated using the following formula: wavelength = wave velocity/frequency. Wavelength usually is expressed in units of meters. The symbol for wavelength is the Greek lambda λ, so λ = v/f.

Which frequencies are dangerous?
Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).25 мая 2016 г.
What wave frequency is harmful to humans?
The most restrictive limits on whole-body exposure are in the frequency range of 30-300 MHz where the human body absorbs RF energy most efficiently when the whole body is exposed.
What wavelengths are 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.
