Question

from the graph shown below identify the sound that will have higher frequency (A/B ) state the reason
​

Answer 1

at a in a low frequency =low pitch =grave sound or low sound

at b. in b high frequency =high pitch =shrill sound or loud sound

so in b frequency is higher

plese mark as brainlist

Answer 2

Answer:

The graph B is correct.

Explanation:

• We can define frequency (f) as: the number of cycles of a wave per unit time.
• The SI unit of frequency is Hertz.
• Frequency is directly proportional to pitch and inversely proportional to wavelength.
• As the wavelength of a wave increases, the frequency decreases.
• Graph A: The wave takes a longer time to complete one cycle, and it has a longer wavelength; hence, its frequency is lower.
• Graph B: The wave takes lesser time to complete one cycle, and it has a shorter wavelength; hence, its frequency is higher.

Conclusion:

Graph B shows a higher frequency.
