Question

Are the following True or False?

1) Snell's Law describes the change in path of a light ray at the interface between two meida: n_1 sin theta_1 = n_2 cos theta_2

2) Electric current going through a solenoid creates a magnetic field parallel to the direction of current.

3) Electric fields lines cross each other.

4) Calibration of the Geiger counter is required due to background radiation.

5) The equivalent resistance R_eq for resistances in parallel is the sum of the individual resistances.

6) The DC ammeter should always be connected in series with the component being measured.

7) Ohm's Law ideally relates current I and voltage V by the linear relationship VI = R.

8) The index of refraction of a glass prism in air is defined as n = sin phi_1 / sin phi_2

9) Moving charge creates a magnetic field.
