Two rods are both precisely 10.000 cm long. Rod "A" is made of aluminum, while Rod "B" is made of steel. The linear expansion coefficient "alpha" is twice as large for aluminum (24 x 10^-6 K^-1) than for steel (12 x 10^-6 K^-1).
If Rod "A" is heated up by 10 degrees C, and Rod "B" is heated up by 20 degrees C, which one will be longer?
A) The aluminum rod ("A")
B) The steel rod ("B")
C) They will expand by the same amount,

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
