Speed of Light ✔Correct Answer-3 x 10^8 m/s or 300,000 km/s.
Wavelength (λ) ✔Correct Answer-Distance between successive wave crests.
Frequency ✔Correct Answer-Number of wave crests passing a point per second.
Speed Formula ✔Correct Answer-Wavelength x Frequency.
Short Wavelength ✔Correct Answer-Associated with high frequency and high energy.
Long Wavelength ✔Correct Answer-Associated with low frequency and low energy.
Stefan-Boltzman Law ✔Correct Answer-E = σT^4, particular amount of EM radiation emitted
by an object depends primarily on the temperature of the object
Wien's Displacement Law ✔Correct Answer-λmax = 3000/T, peak emission wavelength when
T=Temperature in Kelvin
Black Body ✔Correct Answer-Perfect absorber and emitter of radiation.
Selective Absorbers ✔Correct Answer-Materials that absorb and emit specific wavelengths.
Infrared Radiation ✔Correct Answer-Radiation emitted by Earth, longer wavelengths.
Greenhouse Effect ✔Correct Answer-Retention of infrared radiation by the atmosphere.
CO2 and H2O ✔Correct Answer-Gases that absorb and emit infrared radiation.
Translucent Infrared Radiation ✔Correct Answer-Partially absorbed by the atmosphere.
Planet without Atmosphere ✔Correct Answer-Radiative equilibrium without atmospheric
interference.
Planet with Atmosphere ✔Correct Answer-Higher temperature due to selective absorbers.
, Average Surface Temperature of Venus ✔Correct Answer-480 °C or 900 °F.
