Introduction

In physics, the ratio of distance, frequency, and wavelength is a fundamental concept that helps us understand the behavior of waves. The ratio of distance to frequency, denoted as d:f, and the ratio of frequency to wavelength, denoted as f:w, are two important ratios that are often used in calculations. In this article, we will explore how to write the ratio of distance, frequency, and wavelength in its simplest form.

The Given Ratios

We are given two ratios:

The ratio of distance to frequency, d:f, is 2:5.
The ratio of frequency to wavelength, f:w, is 4:3.

Writing the Ratio in Its Simplest Form

To write the ratio of distance, frequency, and wavelength in its simplest form, we need to find the least common multiple (LCM) of the two given ratios. The LCM is the smallest number that is a multiple of both numbers.

Step 1: Find the LCM of the Two Ratios

To find the LCM of the two ratios, we need to first find the prime factors of each ratio.

The prime factors of 2:5 are 2 and 5.
The prime factors of 4:3 are 2, 2, and 3.

Step 2: Identify the Common Prime Factors

The common prime factors of the two ratios are 2 and 5.

Step 3: Multiply the Common Prime Factors

To find the LCM, we multiply the common prime factors.

The LCM of 2:5 and 4:3 is 2 × 2 × 3 × 5 = 60.

Step 4: Write the Ratio in Its Simplest Form

Now that we have found the LCM, we can write the ratio of distance, frequency, and wavelength in its simplest form.

The ratio of distance to frequency, d:f, is 2:5.
The ratio of frequency to wavelength, f:w, is 4:3.
The ratio of distance, frequency, and wavelength, d:f:w, is 2 × 2 × 3:4 × 2 × 3:3 × 5 = 12:24:15.

Simplifying the Ratio

We can simplify the ratio by dividing both numbers by their greatest common divisor (GCD).

The GCD of 12, 24, and 15 is 3.
The simplified ratio is 12 ÷ 3:24 ÷ 3:15 ÷ 3 = 4:8:5.

Conclusion

In conclusion, the ratio of distance, frequency, and wavelength in its simplest form is 4:8:5.
