How do generators produce electricity

generators produce electricity via electromagnetic induction

What is the meaning of measurement of loudness

Units used to measure loudness are Sone (loudness N) and Phon (loudness level L). Scroll down to related links and look at "Loudness - Wikipedia" and "Sound level change and the change of the respective factor of volume and loudness"

What is the term that describes the number of waves that move though a given point over time

frequency

In which type of waves do the particles in a medium vibrate in the same direction the wave is moving

longitudinal waves

Which characteristic of a wave describes the greatest distance a wave vibrates from a resting position

amplitude

What is the term for the small packets of energy emitted from light

Photons

Which term describes substances that absorb some wavelengths of light

pigments

Which type of waves are combination waves that occur at the boundary between two media

Surface Waves

Which of these waves would you expect to have the greatest wave speed

a wave with long wavelength and high frequency.

Which of the following is true of sound waves

sound waves require a medium to transfer energy

FOR A+ USERS THE ANSWER IS Sound waves travel in all directions
sound waves require a medium to transfer energy

-- They are longitudinal waves and material medium is required for their propagation.

What causes refraction-

Refraction is caused by light crossing from one medium to another.

What occurs when two or more waves occupy the same space at the same time-

When two or more waves occupy the same space at the same time, an interference pattern is created.

What produces standing waves-

Standing waves are the result of an interference of two waves that are traveling along the same medium in opposite directions.

Which of these statements about the EM spectrum is false

most of the EM spectrum is visible light.
