Homework Statement: Lens questions. Homework Equations: idk Hello, so I was wanting to use a laser beam and purchase a few lens' online for a project and wanted to get something similar to the image below, where i would end with a horizontal light ray i was wondering if anyone knows the...

Hey, so I'm just wondering what are the formulas needed to calculate the temperature of a wire after x amount of time as an electrical current is passed through it. I know how to solve for it... I just forgot the formulas. Thanks

1. The two apparatus that could be used is a diffraction gradient and a prism 2. For the prism - The wave properties of light are dispersion and recombination For the diffraction gradient - The wave properties of light are destructive interference, diffraction and crest and troughs 3...

Homework Statement Can the equation E = pc be applied to particles? Why or why not?Homework EquationsThe Attempt at a Solution It can be applied to particles that DONT have a rest mass (photons, which are particles). It can not be applied to particles that have a rest mass (almost everything).

Name the two methods that will produce a spectrum from white light. Compare the methods based on the· type of apparatus used · wave properties involved · mathematical calculations used to describe the process

I think it might be wavelength and frequency can anyone let me know if I am correct

Homework Statement What quantity measured in the Compton effect experiment show the wave-particle duality of light? Homework EquationsThe Attempt at a Solution the question is out of 2 marks and all I can think about is momentum is there anything I am missing or am i completely wrong?

Homework Statement 1. wave properties of light in a prism experiment? 2. wave properties of diffraction in a prism experiment? 3.name one apparatus that uses diffraction Homework Equations The Attempt at a Solution 1. The wave properties of light are dispersion and recombination 2. The wave...

in a uniform e-field the acceleration would be constant but in a non-uniform field it would accelerate at an increasing rate? Is this correct?

Homework Statement Describe the motion of a test charge in a non-uniform electric field.By considering the electric forces acting and Newton’s second law, explain the type of motion occurring in a non-uniform electric field. Homework EquationsThe Attempt at a Solution I wrote that the...

Homework Statement Point P is collinear with a +2.80 μC charged particle and a -8.50 μC charged particle as shown in the diagram below. Point P is 10 cm to the left of the positive charge and 20 cm to the left of the negative charge. What is the electric field at point P...

Aight thanks

Homework Statement What is the distance between two charges of - 5.00 C each if the force of electrostatic repulsion acting on them is 4.00 x 10^3 N?Homework Equations F=kq1q2/r^2 The Attempt at a Solution i got 7.5km... I am not sure if that's right

I don't know how I missed that THANKS! it should be neutral right?

Homework Statement Explain the circumstances that enable a particle to move un-deflected with uniform motion through an electric field if it is given an initial velocity perpendicular to the electric field. Assume the electric field is the only field present.[/B] Homework EquationsThe Attempt...
