Title: Electromagnetic Spectrum 1 Electromagnetic Spectrum 2 What is the EM Spectrum? 186,000 miles per second But the speed can be slower ... At slower speeds the wavelength is shorterfor the same frequency. We can work out the wavelength: wavelength = speedfrequency Electromagnetic Spectrum. Is this correct? (As one goes up, the other goes down.) The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. But how waves interact with matter depends on their energy and the type of matter. These tags are fully printable, compact, resistant to harsh environmental effects, and … Electromagnetic Spectrum The electromagnetic spectrum (EMS) is the general name given to the known range of electromagnetic radiation. Wavelength is measured in meters. The electromagnetic spectrum can be expressed in terms of energy, wavelength or frequency.

These include infrared, visible, UV, microwave, x-rays, gamma rays, etc. The electromagnetic spectrum consists of the totality of all electromagnetic radiation.Made up of photons, everything in the electromagnetic spectrum is sometimes referred to as light, although the word sometimes refers to only the human-visible portion of the electromagnetic spectrum.. Radio telescopes detect radio waves, a form of electromagnetic radiation, from space. The image below shows the names given to different regions of the EMS. The frequency is the number of waves which pass a point in space each second. Radio waves are EM (Electromagnetic)waves that have wavelengths between 1 millimeter and 100 kilometers (or 300 GHz and 3 kHz in frequency). This rate of change is the frequency ν measured in cycles per second—namely, in hertz. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus.
