What is the wavelength? {Ans: The distance between the same point on two adjacent waves}How are loudspeakers setup? {Ans: A coil of wire is wrapped around one pole of a permanent magnet which is surrounded by the other pole of the magnet. This coil is attached to a paper cone}How can radiation be measured? {Ans: A Geiger-Muller Tube and Counter}What are ohmic conductors? {Ans: One whose resistance does not change with current}What can an oscilloscope show in the generator effect? {Ans: The change in potential difference generated over time - AC will cross the horizontal axis in waves whereas DC will not}How do wavefronts change during refraction? {Ans: When entering an optically denser medium, the lines will become closer together to represent the decrease in wavelength}What is a transverse wave? {Ans: A wave where the oscillations are perpendicular to the direction of energy transfer}What's the difference between permanent and induced magnets? {Ans: Permanent generate their own magnetic field whereas induced are turned into magnets in the presence of a magnetic field}How are protostars formed? {Ans: Protostars form from a cloud of dust and gas (nebula) due to gravitational forces pulling it
