PHY 109: Astronomy

Explore how a mass spectrometer works by analyzing an ion's path through the device. Understand the relationship between electric and magnetic fields in determining the ion's trajectory. Learn to compute the radius of an ion's path within the mass spectrometer.

Uncover the fascinating science behind peephole lenses, including the principles of light refraction and observer positioning that allow for an extensive field of vision through a hotel room door.

Analyze the physics of a falling squirrel, calculating its velocity upon hitting the ground and the deceleration due to limb bending.

Uncover the methodology behind determining an unknown light's wavelength using the double slit experiment. Understand how fringe spacings relate to the light's properties. Find out the significance of second-order fringes and their measurements.

Join us on the baseball field as we calculate the physics of a ground ball throw to second base. In this video, we determine the distance from the shortstop to the second baseman and the vertical drop of the ball. Explore the principles of projectile motion in sports.

Explore the nuances of Newton's third law and learn how the choice of the 'system of interest' influences force pair cancellation.
