The wavelength of a wave doubles as it travels
from medium a into medium b. compared to the
wave in medium a, the wave in medium b has
(1) half the speed
(2) twice the speed
(3) half the frequency
(4) twice the frequency

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.

Ascientist notices that an oil slick floating on water when viewed from above has many different colors reflecting off the surface, making it look rainbow-like (an effect known as iridescence). she aims a spectrometer at a particular spot and measures the wavelength to be 750 nm (in air). the index of refraction of water is 1.3
