Regarding this, which region of the electromagnetic spectrum has the shortest wavelength?

Gamma Rays

Beside above, which color has the longest wavelength?

red

What is the wavelength range of the electromagnetic spectrum?

Visible light has a wavelength range from ~400 nm to ~700 nm.

The EM spectrum.
Type of Radiation Frequency Range (Hz) Wavelength Range
x-rays 1017 - 1020 1 nm - 1 pm
ultraviolet 1015 - 1017 400 nm - 1 nm
visible 4 - 7.5*1014 750 nm - 400 nm
near-infrared 1*1014 - 4*1014 2.5 μm - 750 nm

What are the 7 types of electromagnetic spectrum?

The different types of electromagnetic radiation shown in the electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible light, ultraviolet radiation, X-rays, and gamma rays.

### Do humans emit radio waves?

Our body itself also emits infrared radiation (and even some radio waves) because it is warm. You can read more about this in the section “Mobile telephone”. While infrared light and radio waves are converted to heat, electromagnetic fields with (extremely) low frequency produce an electric current in the body.

### Which type of waves has the highest 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 has longest wavelength?

Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.

### Why is it called the electromagnetic spectrum?

Scientists call them all electromagnetic radiation. The waves of energy are called electromagnetic (EM) because they have oscillating electric and magnetic fields. Scientists classify them by their frequency or wavelength, going from high to low frequency (short to long wavelength).

### What kind of radiation is light with a wavelength of 1 cm?

Region Wavelength Frequency
Visible (red) 700 nm 4.3 × 1014 Hz
Infrared 10000 nm 3 × 1013 Hz
Microwave 1 cm 30 GHz

### Which types of light travels at the fastest speed?

Radio waves have the longest wavelength. None of those present has the highest speed. All photons travel at the same speed, at the speed of light, regardless of energy.

### How do we use the electromagnetic spectrum in everyday life?

Behaviour and uses of electromagnetic waves
2. Microwaves. Microwaves are used for cooking food and for satellite communications.
3. Infrared.
4. Visible light.

Gamma rays

### What is the electromagnetic spectrum simple definition?

The Electromagnetic Spectrum. The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.

### What is the wavelength of black?

Visible light is electromagnetic radiation with wavelengths ranging from roughly 400 and 700 nanometers. In physics, a color is visible light with a specific wavelength. Black and white are not colors because they do not have specific wavelengths.

Radio waves have the longest wavelengths in the electromagnetic spectrum. These waves can be longer than a football field or as short as a football. Radio waves do more than just bring music to your radio. They also carry signals for your television and cellular phones.

### What part of the electromagnetic spectrum can we see?

The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.

### What is the electromagnetic spectrum of light?

The electromagnetic spectrum is the term used by scientists to describe the entire range of light that exists. From radio waves to gamma rays, most of the light in the universe is, in fact, invisible to us! Light is a wave of alternating electric and magnetic fields.

### What is the electromagnetic spectrum used for?

Astronomers use the entire electromagnetic spectrum to observe a variety of things. Radio waves and microwaves – the longest wavelengths and lowest energies of light – are used to peer inside dense interstellar clouds and track the motion of cold, dark gas.
