Let's look at the properties of materials that cause a resistor to resist the flow of current. Created by David SantoPietro.
Explanation of the second law of thermodynamics.
Conservative replication, dispersive replication, and semi-conservative replication.
What happens when there's only one hole? Created by David SantoPietro.
How to find the amplitude, period, frequency, and wavelength for a sound wave. Created by David SantoPietro.
In this video David explains what specific gravity means. He also shows how to calculate the value for specific gravity and use it to determine the percent of an object that will be submerged while floating.
How fast does sound actually travel? Created by David SantoPietro.
Find out why you can make music by blowing into empty bottles. Created by David SantoPietro.
Find out why a flute makes such specific notes. Created by David SantoPietro.
Thin film interference occurs when light waves reflecting off the top and bottom surfaces of a thin film interfere with one another. This type of interference is the reason that thin films, such as oil or soap bubbles, form colorful patterns. Created by David SantoPietro.
Let's work out a few details on how thin film interference works. Created by David SantoPietro.
Some examples of using the thin lens equation. Created by David SantoPietro.
Learn about the instruments we use to measure voltage and current. Created by David SantoPietro.
David explains the link between work and kinetic energy. Created by David SantoPietro.
David shows how the area under a force vs. position graph equals the work done by the force and solves some sample problems. Created by David SantoPietro.
David goes through some example problems on the concept of work. Created by David SantoPietro.
Writing nuclear equations for alpha, beta, and gamma decay. Created by Jay.
Let's derive a formula that relates all the variables in Young's double slit experiment. Created by David SantoPietro.
We can see interference in action if we shine laser light through two slits onto a screen. Created by David SantoPietro.
An example problem involving a double slit experiment. Created by David SantoPietro.
