Investigation #1 (How does mass affect period?):
Change the string length to 0.5 m (upper right-hand corner)
Click and drag the pendulum so it has an amplitude of 10°
Change the mass each time you complete a trial
Use the stopwatch to time 10 full cycles of the pendulum
Calculate the period of the pendulum (time to complete one full cycle) by dividing the Time of 10 Cycles by 10.

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
