Earth's atmosphere according to increasing altitude? correct answers Ionosphere, mesosphere, stratosphere, clouds, troposphere Sort the stars by their temperature from cold to hot correct answers Blue, violet, yellow, red Principles of specular reflection? correct answers Object whose image is formed by a flat mirror is = real Angle of incidence = angle of reflection Image by reflection in flat mirror = virtual The normal = 90 degrees Blackbody curves of 4 stars at different temp...

1. through accommodation, your eye can change its refractive power to help it focus images by: changing the shape of the lens itself, via attached ciliary muscles contracting or relaxing it (lesson 13) 2. we have blurry vision in water (such as in a swimming pool) because: - cornea itself is mostly made of water, reducing the difference in indices of refraction (lesson 13) 3. a person born with no (functioning) retina in his eyes would: be completely blind (lesson 13) 4. although the eye and ...

Highest altitude layer to lowest correct answers Ionosphere, mesosphere, stratosphere, troposphere The accurate explanation and confirmation of how aurora are produced came from correct answers Russian and American satellites (late 20th century) measuring activity around Earth's space neighborhood. The number of auroral displays on Earth appears to be correlated with correct answers the sunspot cycle According to the __________ cultural story, the aurora would come down to Earth and...

Our eyes must be able to adjust to changes in total amount of light entering them by a factor of several billion photons. What is their most efficient mechanism for doing so? correct answers Detecting relative differences in detected light levels. Outside during a moonlit night, it is hard for us to distinguish colours in objects because correct answers we have only rods functioning in scotopic illumination, which suffer from the principle of univariance. Combining yellow and blue colour...
