Which table shows the correct medium for a liquid?

Question 19 options:

Table 1

Answer 1

To identify the correct medium for a liquid based on the speeds given in the tables, we need to know the typical speed of sound in a liquid. The speed of sound in water (a common liquid) is approximately 1,481 m/s, but it can vary depending on the temperature and other factors.

Now, let's look at the tables:

- **Table 1**: 3.00 x 10^8 m/s (speed of light) and speed of sound (not specified).
- **Table 2**: 12,000 m/s (speed of sound) and 1.24 x 10^8 m/s (speed of light). The speed of sound here is too high for any common liquid.
- **Table 3**: 343 m/s (speed of sound) and 3.00 x 10^8 m/s (speed of light). This speed is typical for sound in air.
- **Table 4**: 1,481 m/s (speed of sound) and 2.25 x 10^8 m/s (speed of light). The speed of sound here is typical for many liquids.

Based on this analysis, **Table 4** shows the correct medium for a liquid.

So, the answer is:

**Table 4**
