How does diffraction enable somebody to hear your voice from anywhere in the room?
Vilka [71]
Diffraction means spreading out of waves that has the same wavelength as the size of the gap. Sound waves have high wavelength and so it diffracts\spreads out and enables anyone to hear your voice from anywhere outside the room.

For inside the room, the sound waves doesn't actually diffract. They collide with the air particles, causing a series of compressions and rarefactions which spreads out in the air particles and anyone can hear your voice.

Air is the medium for the sound waves to travel.

By starting with a falsifiable hypothesis and proceeding to gather data and ensure replicability, a scientist can contribute to
maksim [4K]

Answer:

theory

Explanation:

<em>A scientist can contribute to the formation of a theory in a particular subject by conducting research along the line of that subject.</em>

Conducting research requires the formation of a hypothesis and testing the hypothesis by conducting a relevant experiment during which data are gathered, analyzed, and interpreted in order to falsify or accept the hypothesis.

A good experiment must be replicate-able. When the same experiment is repeated by different independent researchers and the same conclusion is arrived at, this could potentially lead to the formation of a theory.

<u>Hence, a scientist can contribute to the formation of a theory by conducting an experiment with replicability in order to test a hypothesis.</u>

Find the frequency of the 4th harmonic waves on a violin string that is 48.0cm long with a mass of 0.300 grams
Jlenok [28]

Answer:

The frequency of the 4th harmonic of the string is 481.13 Hz.

Explanation:

When a stretch string fixed at both ends is set into vibration, it produces its lowest sound of possible note called the fundamental frequency.  Under certain conditions on the string, higher frequencies called harmonics or overtones can be produced.

The frequency of the forth harmonic is the third overtone of the string and can be determined by:

          f = \frac{2}{L}\sqrt{\frac{T}{m} }

Given that; L = 48.0 cm = 0.48 m,

                 m = 0.3 g = 0.0003 Kg,

                 T = 4.0 N,

         f = \frac{2}{0.48}\sqrt{\frac{4}{0.0003} }

         f = 4.1667 × 115.4701

           = 481.1252

        f = 481.13 Hz

The frequency of the 4th harmonic of the string is 481.13 Hz.
