In a transverse wave the medium vibrates
A) at right angles to the wave direction
B) in the same direction as the wave***
C)at a 45-degree angle to the wave direction
PLS HELP!!! its a time test!!
Hello l have a Question
When particles vibrate perpendicular to the direction in which the wave travels, the particles move at an angle( )degrees to the direction of the wave.
A- 0
B-45
C-180
D-90
🤷🏻♀️
No.
A wave on a string is transverse for example. The vibration of a guitar string is not up and down the string but perpendicular to it.
A sound wave is longitudinal however, the motion of particles is along the direction of the wave propagation.
By the way, that is why the wave on the guitar string is called "transverse".
To determine the correct answer, let's first understand what a transverse wave is.
A transverse wave is a type of wave that occurs when the particles of the medium move perpendicular (at right angles) to the direction of the wave. This means that the medium vibrates in a direction that is different from the direction the wave is moving.
Now, let's analyze the options provided:
A) at right angles to the wave direction
This option aligns with the definition of a transverse wave. The medium vibrations occur at right angles (perpendicular) to the wave direction. Therefore, this option is correct.
B) in the same direction as the wave
This option contradicts the definition of a transverse wave. In a transverse wave, the medium vibrations occur perpendicular to the wave direction, not in the same direction. Therefore, this option is incorrect.
C) at a 45-degree angle to the wave direction
This option suggests that the medium vibrations occur at a 45-degree angle to the wave direction. However, in a transverse wave, the medium vibrations are always at right angles (perpendicular) to the wave direction, not at a 45-degree angle. Therefore, this option is incorrect.
In conclusion, the correct answer is A) at right angles to the wave direction.
