Properties of Waves

Question 1

longitudinaltransverse✔ both longitudinal and transverse

Revolt · Accepted Answer

C: both longitudinal and transverse

Question 2

Which wave, A or B, has lower energy?

Revolt · Accepted Answer

C: A, because it has a lower amplitude

Question 3

Question 3

Revolt · Accepted Answer

Tara's graphical representation is incorrect. The relationship between the amplitude of a wave and its energy is not linear; instead, the energy of a wave is proportional to the square of its amplitude (E ∝ A²). Therefore, her graph should show an exponential or parabolic curve rather than a straight line to accurately represent how energy increases as amplitude increases.

Revolt · Accepted Answer

Sound travels faster in a warm room. This is because higher temperatures cause the air particles to move faster and collide more often, which increases the speed of energy transfer through the medium.
