Select the correct definition from the list below for a transverse wave.

• The oscillations of a transverse wave are perpendicular to the direction in which the waves transfer energy.

• The oscillations of a transverse wave are parallel to the direction in which the waves transfer energy.

• The oscillations of a transverse wave are at 45o to the direction in which the waves transfer energy.

• The oscillations of a transverse wave are in the same direction in which the waves transfer energy.

Answer explanation

a. The oscillations of a transverse wave are perpendicular to the direction in which the waves transfer energy.

What is the relationship between amplitude and energy?

• The bigger the amplitude of the waves, the more energy the waves carry.

•  The smaller the amplitude of the waves, the more energy the waves carry.

• Amplitude and energy are not related, they have no effect on each other.

• Doubling the amplitude of the waves, reduces the amount of energy the wave carries by half.

8. Compare longitudinal waves from transverse waves

Answer explanation

A longitudinal wave vibrates in the same direction as the wave travels, while a transverse wave vibrates perpendicular to the direction of wave propagation.

Josey is conducting a lab investigating the effects of acid rain. While reading the lab instructions, she notices the safety symbol shown above. What is the meaning of this safety symbol?

Scientists perform many trials for each experiment because —

• they want to improve their public image

• they want to improve the reliability of the results

• they have to rewrite the hypothesis

• they have to decide how to publish the data
