The average speed of sound is 343 m/s. If a wavelength of a certain sound is 1.3 m, what is the frequency of that sound?

The average speed of sound is 343 m/s. If a pitch is heard at 500 Hz, what is the wavelength of that sound?

What is the wavelength of a wave if it moves at 100 m/s and has a frequency of 33 Hz?

Explanation:

(A) Speed of sound is 343 m/s

Wavelength of a sound wave is 1.3 m

Frequency,

(B) The average speed of sound is 343 m/s.

Pitch of the sound is 500 Hz

Wavelength,

(C) Speed of wave is 100 m/s

Frequency of wave is 33 Hz

Wavelength,

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
