Answer:
1. A
2. C
3. C
4. D
5. C
Explanation:
1. Waves transfer energy away from the source or starting place, of the energy.
2. Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.
3. A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.
4. Wavelength can be defined as “the distance between two adjacent points in a wave that moves in-phase (or in step).

Given Data:
f ( Frequency ) = 410 Hz
λ ( Wavelength ) = 0.8 m
s ( speed ) = ? unknown
Solution:
We can use the formula of wave speed which is Speed = Wavelength × Wave Frequency ( s = λf )
Solution:
s = λf
= 0.8 m × 410 Hz
= 328 m/s
