Space Technology & Electromagnetic Spectrum Quiz on Monday 3/11

Pages

The following information will be covered on Monday’s quiz:

EMS

The sequence (order) of electromagnetic radiation from longest wavelength to shortest wavelength:EMS
Radio, microwave, infrared, visible light, ultraviolet, x-ray, gama ray (Click here for a mnemonic device to help you remember the order.)

What is frequency:
the number of waves per time interval, such as 3 waves per second

What is wavelength:
the distance between two identical adjacent points in a wave.  For example, the distance between one peak or crest of a wave of light, heat, or other energy and the next corresponding peak or crest.

The inverse relationship of wavelength and frequency:frequency-wavelength
As wavelength decreases, the frequency of waves increases (more waves per second).
Shorter wavelength, higher frequency | Longer wavelength, lower frequency.

Types of Telescopes

Reflection Telescope (optical):
light from on object in space is reflected off of mirrors inside the telescope.  The Hubble Space Telescope is an example of a reflecting telescope.

Refraction Telescope(optical):
light from an object in space in bent (refracted) through an objective lens

Radio Telescope:
uses a large curved dish to collect and record radio waves traveling through space.

Spacecraft:

Artificial Satellite:
any human-made object that orbits another object in space

Space Shuttle:
reusable spacecraft that transports astronauts, satellites, and other materials to and from space

Space Probe:
an instrument that gathers information and sends the data back to Earth. Unlike satellites that orbit earth, space probes travel far into the solar system.

Space Station:
large artificial satellite that provides support systems, living quarters, and equipment so that humans can live and work in space and conduct research not possible on Earth. The International Space Station, for example, is a permanent laboratory designed for use in long-term research.
