CEM 141 MSU Exam 2 Questions and Answers Already Passed Lights acts as what? Particle and wave. Wavelength The distance (m) of waves from peak to peak. Short: x-ray (red), long: infrared (blue) Short - higher energy Long - lower energy Frequency (V) The number of wavefronts per second. Highest: x-ray Velocity of Light C = 3.00 X 10^8 = wavelength X frequency Amplitude The intensity, height of peaks of waves. Highest: blue light Energy of Wave (J) Increases as frequency i...

What are the advantages of remote sensing? - - covers large areas - repetitively looks at the same area - sees things that the human eye can't - sees many parts of the EM spectrum simultaneously - provides geo-references What are some non-military applications of remote sensing? - - land use mapping - forest and agriculture applications - telecommunication planning - environmental applications - hydrology coastal mapping - urban planning - emergencies and hazards Definition of remot...

What is the most familiar and far-reaching mass communication medium in the world? - Answer-radio What is the most widely available medium of mass communication? - Answer-radio What was the original use/function of radio? - Answer-person-to-person communication How was money originally made in the radio industry? - Answer--by the selling of radios -most money made by RCA When the original source of revenue in the radio industry proved insufficient, what two developments addressed t...

What is the speed of light? - Light can travel enormous distances under short periods of time. It is faster than any other phenomenon. It takes about 8 minutes for light to travel from the Sun to Earth. The speed of light in a vacuum is c=3x10^8 m/s. Why is light such an important tool for astronomers? - Because light is how we learn about distant objects without travelling there. It is also a measuring took of astronomy. Light is a wave and a particle. How are different kinds of light wave...
