Questions from Modern Physics

Q: In high-energy physics, new particles can be created by

In high-energy physics, new particles can be created by collisions of fast-moving projectile particles with stationary particles. Some of the kinetic energy of the incident particle is used to create...

Q: You place an object alongside a white screen, and a plane

You place an object alongside a white screen, and a plane mirror is 60.0 cm to the right of the object and the screen, with the surface of the mirror tilted slightly from the perpendicular to the line...

Q: A lens forms a real image that is 214 cm away from

A lens forms a real image that is 214 cm away from the object and 1 2 3 times its height. What kind of lens is this, and what is its focal length?

Q: For a spherical mirror, if s = f, then s

For a spherical mirror, if s = f, then s′ =∞, and the lateral magnification m is infinite. Does this make sense? If so, what does it mean?

Q: Figure P34.80 shows an object and its image formed by

Figure P34.80 shows an object and its image formed by a thin lens. a. What is the focal length of the lens, and what type of lens (converging or diverging) is it? b. What is the height of the image?...

Q: An imperial spaceship, moving at high speed relative to the planet

An imperial spaceship, moving at high speed relative to the planet Arrakis, fires a rocket toward the planet with a speed of 0.920c relative to the spaceship. An observer on Arrakis measures that the...

Q: A transparent rod 30.0 cm long is cut flat at

A transparent rod 30.0 cm long is cut flat at one end and rounded to a hemispherical surface of radius 10.0 cm at the other end. A small object is embedded within the rod along its axis and halfway be...

Q: a. How fast must you be approaching a red traffic light

a. How fast must you be approaching a red traffic light (λ = 675 nm) for it to appear yellow (λ = 575 nm)? Express your answer in terms of the speed of light. b. If you used this as a reason not to g...

Q: The radii of curvature of the surfaces of a thin converging meniscus

The radii of curvature of the surfaces of a thin converging meniscus lens are R1 = +12.0 cm and R2 = +28.0 cm. The index of refraction is 1.60. a. Compute the position and size of the image of an obj...

Q: An object to the left of a lens is imaged by the

An object to the left of a lens is imaged by the lens on a screen 30.0 cm to the right of the lens. When the lens is moved 4.00 cm to the right, the screen must be moved 4.00 cm to the left to refocus...
