A wave has a wavelength of 7 mm and a frequency of 9 hertz. What is its speed?

Physics

Snezhnost [94]3 years ago
8 0
Speed of wave = Frequency x Wavelength
so Speed = 0.7 x 9 = 6.3

remember the calculations must be done in their Basic SI units.
therefore, you have to convert 7 mm to meters which becomes 0.7 meters

Ten students stand in a circle and are told to make a transverse wave. What best describes the motion of the students? Each stud
Bond [772]

Lifting hands and the down by one student at a time best describe the presentation of the transverse wave by students. Option D is correct.

<h3>What is a Transverse wave?</h3>
  • The wave in which the oscillation of particles is is perpendicular to the direction of energy transfer.

  • The students can make a transverse wave by raising their hands up and then down, one student at a time.

  • The raised hand represents the oscillation of particles while the sequence of the raising hand represents the direction of energy transfer.

Therefore, lifting hands and the down by one student at a time best describe the presentation of the transverse wave by students.

Explain the Big Bang and how it started
AlexFokin [52]

The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now (and it could still be stretching).
