First harmonic question ( from Aqa paper)

In summary, the first harmonic is the lowest frequency produced by a vibrating object, also known as the fundamental frequency. It is calculated by dividing the speed of sound by the length of the object and is the base frequency for all other harmonics. The first harmonic determines the pitch of the sound and can be altered by changing the length, tension, or density of the vibrating object.

it is the multiple choice question number 13
Relevant Equations
first harmonic equation
The answer is f/square root 2

If F = 1/2l * square root ( Tension/ mass per unit length )
---------> this becomes I am assuming 1/2l * square root ( length * Tension/ mass )
this would give an answer of F

yet the answer is F/ square root (2)

FAQ: First harmonic question ( from Aqa paper)

What is the First Harmonic Question?

The First Harmonic Question is a type of question that appears in Aqa papers for science subjects. It is designed to test a student's understanding of the first harmonic, which is the fundamental frequency of a wave.

What is the purpose of the First Harmonic Question?

The purpose of the First Harmonic Question is to assess a student's knowledge and understanding of the first harmonic and its properties. It is also used to test their ability to apply this knowledge to solve problems.

How is the First Harmonic Question typically structured?

The First Harmonic Question usually involves a scenario or problem related to waves and the first harmonic. It may require students to calculate the first harmonic frequency, wavelength, or speed of a wave, or to explain the concept of the first harmonic in their own words.

What are some common misconceptions about the First Harmonic Question?

One common misconception about the First Harmonic Question is that it only applies to sound waves. In reality, the first harmonic can be found in any type of wave, including electromagnetic waves. Another misconception is that the first harmonic is the loudest or strongest frequency, when in fact it is the lowest frequency present in a wave.

How can I prepare for the First Harmonic Question?

To prepare for the First Harmonic Question, it is important to have a clear understanding of the first harmonic and its properties. Reviewing class notes, practicing sample questions, and seeking help from a teacher or tutor can also be helpful. It is also important to read the question carefully and show all steps in your calculations to ensure accuracy.
