Gino made a table to describe parts of the electromagnetic spectrum.

| Wave | Frequency | Wavelength |
|--------------|------------|--------------|
| Ultraviolet | High | Long |
| Radio waves | Very low | Very long |
| Infrared | Low | Long |
| X-rays | High | Short |

What mistake did Gino make?

A. X-rays should have a low frequency and a long wavelength.
B. Infrared light should have a high frequency, not a low frequency.
C. Radio waves should have a very high frequency and a very short wavelength.
D. Ultraviolet light should have a short wavelength, not a long wavelength.

To address the mistakes in Gino's table regarding the electromagnetic spectrum, we must first identify the correct characteristics of each type of wave. Here is the corrected information for each type of wave:

1. X-rays should have a high frequency and a short wavelength.
2. Infrared light should have a high frequency, not a low frequency.
3. Radio waves should have a very low frequency and a very long wavelength.
4. Ultraviolet light should have a short wavelength, not a long wavelength.

Given this corrected information, we can now identify the mistakes present in Gino's table as it stands:

### Mistakes in Gino's Table:

1. Ultraviolet (UV):
- Gino wrote: High frequency, Long wavelength
- Mistake: The wavelength should be short, not long.

2. Radio waves:
- Gino wrote: Very low frequency, Very long wavelength
- Gino's entry is correct; there is no mistake here.

3. Infrared (IR):
- Gino wrote: Low frequency, Long wavelength
- Mistake: The frequency should be high, not low.

4. X-rays:
- Gino wrote: High frequency, Short wavelength
- Gino's entry is correct; there is no mistake here.

### Summary of Mistakes:

- Ultraviolet (UV):
- Mistake: Long wavelength (should be Short wavelength)

- Infrared (IR):
- Mistake: Low frequency (should be High frequency)

### Corrections:
- Ultraviolet (UV):
- Correct: High frequency, Short wavelength

- Infrared (IR):
- Correct: High frequency, Long wavelength

### Corrected Table:

After addressing the mistakes, the corrected table should look like this:
\begin{tabular}{|l|l|l|}
\hline \multicolumn{1}{|c|}{ Wave } & \multicolumn{1}{c|}{ Frequency } & \multicolumn{1}{c|}{ Wavelength } \\
\hline Ultraviolet & High & Short \\
\hline Radio waves & Very low & Very long \\
\hline Infrared & High & Long \\
\hline X-rays & High & Short \\
\hline
\end{tabular}

By correcting these mistakes, the table now accurately reflects the properties of each type of wave in the electromagnetic spectrum.
