What is an electromagnetic wave Grade 10?

Electromagnetic radiation has both a wave and a particle nature. Electromagnetic waves travel at a speed of approximately 3×108 m·s−1 in a vacuum. The Electromagnetic spectrum consists of the following types of radiation: radio waves, microwaves, infrared, visible, ultraviolet, X-rays, gamma-rays.

What is electromagnetic waves in simple words?

Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

What are electromagnetic waves kid definition?

Electromagnetic waves are a form of energy waves that have both an electric and magnetic field. Electromagnetic waves are different from mechanical waves in that they can transmit energy and travel through a vacuum.

What are electromagnetic waves Definition & Types?

Definition of electromagnetic wave : one of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity and that include radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

What is electromagnetic spectrum Slideshare?

The electromagnetic waves are grouped into types that have similar wavelengths and so have similar properties. Electromagnetic waves form a continuous series in order of changing wavelength, frequency and energy. This series is called the electromagnetic spectrum.

What is electromagnetic spectrum answers?

What Is the Electromagnetic Spectrum? The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see. Other types of light include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays and gamma rays — all of which are imperceptible to human eyes.

What is electromagnetic wave example?

Radio waves, microwaves, visible light, and x rays are all examples of electromagnetic waves that differ from each other in wavelength. These waves are also called “electromagnetic radiation” because they radiate from the electrically charged particles.

Which is an example of an electromagnetic wave?

What are the uses of electromagnetic waves?

Uses of Electromagnetic Waves

• Radio waves – radio and television.
• Microwaves – satellite communications and cooking food.
• Infrared – Electrical heaters, cooking food and infrared cameras.
• Visible light – Fibre optic communications.
• Ultraviolet – Energy efficient lamps, sun tanning.
• X-rays – Medical imaging and treatments.

What are electromagnetic waves for middle school?

Electromagnetic waves are waves that can travel through the emptiness of space, at the speed of light. The seven types of electromagnetic waves are radio waves, microwaves, infrared waves, visible light waves, ultraviolet waves, x-rays and gamma rays.

Which of the following is an electromagnetic wave?

The correct answer is option 1 i.e Infrared rays. Waves that consist of vibrating electric and magnetic fields are called electromagnetic waves. The examples of electromagnetic waves are: Radio waves.

What do students learn in the electromagnetic spectrum course?
