Introduction

In the realm of physics, frequency is a fundamental concept that plays a crucial role in understanding various phenomena. It is defined as the number of oscillations or cycles per second of a wave, measured in Hertz (Hz). In this article, we will delve into the concept of frequency and explore which of the given options is the smallest frequency.

What is Frequency?

Frequency is a measure of the number of oscillations or cycles per second of a wave. It is an essential parameter in understanding various physical phenomena, including sound waves, light waves, and other types of waves. The frequency of a wave is typically denoted by the symbol f and is measured in Hertz (Hz).

Types of Frequency

There are several types of frequency, including:

Audio frequency: This type of frequency ranges from 20 Hz to 20,000 Hz and is associated with sound waves.
Radio frequency: This type of frequency ranges from 3 kHz to 300 GHz and is associated with radio waves.
Microwave frequency: This type of frequency ranges from 300 MHz to 300 GHz and is associated with microwave radiation.
Infrared frequency: This type of frequency ranges from 300 GHz to 400 THz and is associated with infrared radiation.
Visible frequency: This type of frequency ranges from 400 THz to 800 THz and is associated with visible light.
Ultraviolet frequency: This type of frequency ranges from 800 THz to 30 PHz and is associated with ultraviolet radiation.
X-ray frequency: This type of frequency ranges from 30 PHz to 30 EHz and is associated with X-ray radiation.
Gamma-ray frequency: This type of frequency ranges from 30 EHz to 30 ZHz and is associated with gamma-ray radiation.

Comparing the Given Options

Now that we have a basic understanding of frequency, let's compare the given options:

Option A: $9.1 \times 10^3 \, \text{Hz}$
Option B: $2.1 \times 10^8 \, \text{Hz}$
Option C: $5.4 \times 10^5 \, \text{Hz}$
Option D: $3.55 \times 10^2 \, \text{Hz}$

To determine which of these options is the smallest frequency, we need to compare their values.

Calculating the Values

Let's calculate the values of each option:

Option A: $9.1 \times 10^3 \, \text{Hz} = 9,100 \, \text{Hz}$
Option B: $2.1 \times 10^8 \, \text{Hz} = 210,000,000 \, \text{Hz}$
Option C: $5.4 \times 10^5 \, \text{Hz} = 540,000 \, \text{Hz}$
Option D: $3.55 \times 10^2 \, \text{Hz} = 355 \, \text{Hz}$

Conclusion

Based on the calculations, we can see that Option D has the smallest frequency, with a value of 355 Hz.

Conclusion

In conclusion, frequency is a fundamental concept in physics that plays a crucial role in understanding various phenomena. By comparing the given options, we have determined that Option D has the smallest frequency, with a value of 355 Hz. This article has provided a basic understanding of frequency and its types, as well as a comparison of the given options. We hope that this article has been informative and helpful in understanding the concept of frequency.
