CONS 127 EXAM SCRIPT FINAL PAPER
2026 FULL QUESTIONS AND CORRECT
ANSWERS
◉ RADARSAT Constellation
Answer: 3-8 Pixel
-Active remote sensing
-Synthetic Aperture Radar
Designed to monitor
- ice
-Surface wind
-oil pollution
- ships
- disasters
-Ecosystems
◉ Radiation fundamentals
Answer: Unit of Radiation is the Photon
- Photons are released from objects when matter is excited thermally
(gets hot) or is engaged in a nuclear process
,-Photons are also absorbed and reflected by matter
-When wavelength increases the frequency lowers
Wavelength is crest to crest frequency is how many crests pass a
point in a certain amount of time
*lower frequency = less energy
*higher frequency = More energy
◉ Types of waves and their lengths. Longest to Shortest
Answer: Radio waves = 30 cm, atmosphere almost completely
transparent
Microwave- 0.1-30 cm, Atmosphere mostly transparent
Thermal/ Far infrared = 3.0 - 10,000 um, terrestrially derived,
absorbed by water vapor and c02 in atmosphere
Reflective/ near infrared = 700 -3000 nm. High absorption by water
vapor in the atmosphere
,Visible = 400- 700 nm relatively speaking earths atmosphere almost
completely transparent
Ultraviolet = 1-400 nm, Most blocked by earths atmosphere except
300-400 nm
Gamma and X- rays = < 10A, Earths atmosphere blocks this radiation
almost completely
◉ Radio waves
Answer: Lol longest waves >30 cm
- Radio receives these electromagnetic radio waves and converts
them to mech vibrations in the speaker to create the sounds ya hear
- Radio telescopes can view astronomical objects like planets and
stars because they have changing magnetic fields which produce
radio waves
- Also has the advantage that sunlight, clouds and rain do not affect
observations
- Radio telescopes are big yall
, - Astronomers often combine several small telescopes into an array
◉ Microwaves
Answer: - Microwave waves are grouped into subsections X, C, L , P
X= interacts with raindrops and clouds
C= Start to revel earths surface ie Forest canopy
L = Show the moisture level of the forest
-Communication satellites use C, X and Ku bands to send signals to a
ground station
Good for studying the earth from space which is what this course is
about yall
◉ Infrared waves
Answer: Divided in to near, mid and far infrared
-We can sense some infrared heat as color
