The Wave Nature of Light
100

This property only depends on the two materials that are in contact with each other.

The coefficient of friction

As you put a heavier mass on a spring and let it oscillate, this happens to the period.  

The period increases

100

The speed of an object in orbit does not depend on this.

The mass of the object

This physicist's experiment proved that Huygen's wave model of light described light's behaviour more accurately than Newton's particle model of light.

This force is always perpendicular to the surface

The normal force

As a skier goes down a mountain, the amount of gravitational potential energy does this.

Decreases

A current flows in a wire east to west.  The magnetic force is to the bottom of the page.  What is the direction of magnetic field?

Into the page.

200

In order for nodal lines to be seen, this has to happen.

Waves have to interfere destructively.

300

You never draw this force on a free-body diagram (FBD).

For circular motion Fc

300

The value that tells us the relative stiffness of a spring.

The spring constant

300

This is the amount of kinetic energy obtained by a 5 C charge as it moves through a potential difference of 8 V.

 40 J

This type of opening creates an interference pattern with narrow maximas and very wide nodal lines.

A diffraction grating

What is the name for net force in circular motion?

Centripetal Force

400

As a spring is stretched out to the right, this is the direction of the spring force.

To the left

400

When a conductor is carrying a current, there will be no force acting on it when the conductor is placed at this angle relative to an external magnetic field.

When they are parallel (0 or 180 degrees)

This type of opening that light goes through produces an interference pattern on a screen that has very defined bright spots, with large dark gaps in between.

A diffraction grating

A person is going upwards in an elevator. How does does their apparent weight compare to the force of gravity as the elevator accelerates upwards?

Apparent weight (normal force) is larger than force of gravity.

500

This type of collision occurs when the two objects stick together and move with the same velocity.

Perfectly inelastic

500

The electric field at a distance of 1.0 m from a charged sphere is 100 N/C.  At what distance is the field 50 N/C?

1.4 m   (square root of 2)

500

This happens to the interference pattern in a double slit experiment as the distance between the slits increases.

The maxima become narrower.
