The musical interval between two tones of frequencies `320 Hz` and `240 Hz` is

Options

A. `80`
B. `(4//3)`
C. `560`
D. `320 xx 240`

Explanation

To find the musical interval between two tones of frequencies 320 Hz and 240 Hz, we can follow these steps:

### Step 1: Identify the Frequencies
We have two frequencies:
- Frequency 1 (f1) = 320 Hz
- Frequency 2 (f2) = 240 Hz

### Step 2: Calculate the Ratio of Frequencies
To find the musical interval, we calculate the ratio of the two frequencies:
\[ \text{Ratio} = \frac{f1}{f2} = \frac{320 \text{ Hz}}{240 \text{ Hz}} \]

### Step 3: Simplify the Ratio
Now we simplify the ratio:
\[ \text{Ratio} = \frac{320}{240} = \frac{32}{24} = \frac{4}{3} \]

### Step 4: Identify the Musical Interval
The ratio of 4:3 corresponds to a perfect fourth interval in music. This means that the musical interval between the two tones is a perfect fourth.

### Final Answer
The musical interval between the frequencies 320 Hz and 240 Hz is a **perfect fourth**.
