The model shows how light waves are transmitted through a transparent substance.

How would the model be different for a sound wave that is being transmitted through the same substance?

• The wavy arrows representing sound waves would have a smaller wavelength

• The wavy arrows representing sound waves would go in the opposite direction

• The atoms in the model would move parallel to the direction of the incoming wave

• The atoms in the model would move perpendicular to the direction of the incoming wave

The diagram shows three types of electromagnetic radiation and their range of frequencies.

Which explanation correctly uses the data in the diagram to show how infrared radiation and ultraviolet radiation are related in terms of energy?

• Ultraviolet radiation has less energy than infrared radiation because energy is inversely proportional tofrequency and the frequency of ultraviolet radiation is higher

• Ultraviolet radiation has more energy than infrared radiation because energy is inversely proportional to frequency and the frequency of ultraviolet radiation is lower

• Ultraviolet radiation has less energy than infrared radiation because energy is proportional to frequency and the frequency of ultraviolet radiation is lower

• Ultraviolet radiation has more energy than infrared radiation because energy is proportional to frequency and the frequency of ultraviolet radiation is higher
