5.06 electromagnetic spectrum guided notes.

a range of wavelengths and frequencies of electromagnetic radiation.

a is the distance between the crest of successive waves.

what is frequency?

what is the relationship between wavelength and frequency of radiation on the electromagnetic spectrum.

at astronomical observations capture this light even better, providing a clearer picture of out galaxy.

Electromagnetic spectrum.

Explanation: It is composed of Gamma rays with the highest energy to radio waves with the lowest energy. It between in descending order (with regard to energy) is; X-rays, Ultraviolet, Visible Light, Infrared, Microwave. The higher the energy level the lower the wavelength and the higher the frequency.

Wavelength

Explanation: Ideally, the wavelength is the distance between two consecutive identical phases of a wave. It could be a peak to another peak or a trough to another trough. Usually, the lower the energy level of the wave, the bigger the wavelength and vice versa. It is measured in meters, millimeters or even picometers depending on the size of the wavelengths.

Explanation: Frequency is the amount of time that it takes for a wave to complete once a cycle, that is, to repeat a phase. Gamma rays have the highest frequency in the electromagnetic spectrum while radio waves have the lowest.

Explanation: Frequency is indirectly proportional to wavelength. This means that the higher the frequency the smaller the wavelength and vice versa. In addition, therefore, converse to wavelength, the higher the energy of a wave, the higher the frequency and vice versa. It is calculated by dividing one (1) with the wavelength of the wave. It is measured in Hertz

Telescopes

Explanation: Their basic principle of telescopes is that they collect as much light as possible from the aperture (this is why the front end is usually large diameter), and then converges this light using lenses and prisms onto a film. This gives a clear picture from which astronomical features can be clearly discerned,

a compound light microscope is used to magnify objects in steps.
