Bookmark or Share- How to Determine g from a T^2 vs. L Graph - Physics ForumsIn summary, the conversation is about a lab where the participants were finding how amplitude, bob mass, and length affect the period T for each time. The question at hand is "From your graph of T^2 vs. L, determine a value for g." The participants discuss their graphs and calculations, trying to figure out how to find g from the given data.
- Energy of an Infinite Square Well - Physics ForumsI was looking over the simple case of a 1D particle restrained inside an infinite square well potential ("particle in a box") and was having some difficulty understanding the relationship between the energy states and the expectation value for the energy. Using the time independent Schrödinger equation and normalizing the wave function I get:
- Time Dependent Wave Function for Particle in Infinite Square WellThe Time Dependent Wave Function for Particle in Infinite Square Well changes with time due to the oscillatory behavior of the wave function. As time increases, the wave function will oscillate between positive and negative values, representing the changing probability of finding the particle in different locations within the well.
- Intensity of laser beam / Inverse square law - Physics ForumsUnderstanding the inverse square law is important in laser technology because it helps us predict how the intensity of a laser beam will change as it travels through space. This is crucial in applications such as laser surgery, where the intensity of the beam needs to be carefully controlled for safety and effectiveness.
- Simple Pendulum: The gradient of the graph of T^2 against lengthThe length of a simple pendulum is directly proportional to its period. This means that as the length of the pendulum increases, so does the time it takes for one complete swing, or period. What is the gradient of the graph of T^2 against length? The gradient of the graph of T^2 against length is the square of the angular frequency, or ω^2.
