PHYS 7307: Introduction to Astronomy

Watch as we explore the fascinating world of thermal expansion in this video. We start with a glass filled to the brim with 350.0 mL of water at a scorching 100.0°C, and then witness the magic unfold as the temperature decreases to a cool 20.0°C. But the real question is, how much more water can we add to the glass? Join us to find out!

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.

Explore the relative strengths of two fundamental forces, the electromagnetic force and the gravitational force, in this enlightening physics tutorial. Learn about Coulomb's law and Newton's law of gravitation, and uncover the significant difference in their constants that makes the electromagnetic force much more powerful than gravity.

Explore the world of high-performance sports cars and learn how to calculate their average acceleration when accelerating and coming to a stop.

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

Uncover the secrets of watch crystals in this video! We convert the frequency of a quartz crystal used in electric watches into its period. Join us to explore the principles of timekeeping and crystal oscillations.
