    Interference from Thin Films: What Happens to Wavelengths in Different Media?

    Ok, I got the answer, but I want to make sure. Is it x_n_ = x/n_2_ where x_n_ is the wavelength in the oil and x is the wavelength in air? n_2_ is the index of refraction of the oil or glass correct? Thanks, by the way.

    Interference from Thin Films: What Happens to Wavelengths in Different Media?

    Homework Statement Light of wavelength x, in air, is incident in air on a film of oil with index of refraction n_oil = 1.45. The film of oil has thickness L, and is spread on glass with an index of refraction n_glass = 1.50. The wavelength of the light in oil will be _____ than the wavelength...

    How Do You Calculate the Reaction at Point A in a Rotating Rod Problem?

    Homework Statement The 4-kg uniform rod ABD is attached to the crank BC and is fitted with a small wheel that can roll without friction along a vertical slot. Knowing that at the instant shown crank BC rotates with an angular velocity of 6 rad/s clockwise and an angular acceleration of 15...

    Linear and anular momentum of a hydrogen electron

    Ok, I found the answer. Linear momentum 4.9821*10^-25 kg * m/s Angular momentum is 4.2182*10^-34 J*s There are also three other parts to the question: Find its kinetic energy, potential energy and total energy. (Use eV) I found its kinetic energy (.850625eV), but I can't find its potential...

    High School Finding the distance an object will travel

    It's not really a problem, I'm doing an experiment where I hit an object with a hammer to see how far it travels. I have to determine whether the mass of the object affects how far it travels. Clearly it does, but I need some kind of relationship to prove it.

    High School Finding the distance an object will travel

    Ok, the force acted on the body for an instant; it struck the object, and the object started moving. It was similar to a hockey stick hitting a puck.

    High School Finding the distance an object will travel

    what is "e" in the equation a = -ve? Oh, also, I only know the force striking the object, I don't know the initial velocity.

    High School Finding the distance an object will travel

    Shooting star, if I use the formula for constant acceleration, then I will end up with this: (V^2-V_0^2)/(2*a) = \Delta x If I use this equation with no acceleration, then I won't be able to get a distance because you can't divide by zero. Or, is the acceleration not zero?

    High School Finding the distance an object will travel

    Hi. I have a question about finding the distance an object will travel along a horizontal surface. If I have a force striking an object directly in the horizontal direction, how would I go about finding how far it will travel? I already have found the frictional force acting on the object...

    High School Where to Find the Coefficient of Friction Between Paper and Plexiglass?

    I don't have a spring scale, but do you have a suggestion on where to look for an alternate method? Thanks.
