To identify the mistakes in Gino's table, let's examine the general characteristics of these types of electromagnetic waves:
1. X-rays: These waves are known for their high frequency and short wavelength. The given table incorrectly states that they have high frequency and short wavelength, which is correct for the frequency but not for the wavelength.
- Correct Characteristics: High frequency, short wavelength (not low frequency and long wavelength).
- Gino's Error: None for X-rays.
2. Infrared Light: This region of the electromagnetic spectrum typically has low to moderate frequency and wavelengths longer than visible light but shorter than microwaves. The table incorrectly states that infrared light has low frequency and long wavelength, which is partially correct because it should be moderate frequency rather than high frequency.
- Correct Characteristics: Low to moderate frequency, long wavelength (partially correct).
- Gino's Error: The frequency should be labeled as 'moderate' rather than 'high'.
3. Radio Waves: These waves have the longest wavelengths and the lowest frequencies in the electromagnetic spectrum. The table incorrectly states that radio waves have a very low frequency and a very long wavelength, which is incorrect in terms of frequency since it should be low, not very low.
- Correct Characteristics: Low frequency, very long wavelength (not very low frequency and very long wavelength).
- Gino's Error: Frequency should be 'low', not 'very low'.
4. Ultraviolet (UV) Light: UV light falls between visible light and X-rays on the electromagnetic spectrum. It has higher frequencies and shorter wavelengths compared to visible light. The table incorrectly states that ultraviolet light has high frequency and long wavelength, but it should have short wavelength instead of long.
- Correct Characteristics: High frequency, short wavelength (not long wavelength).
- Gino's Error: Wavelength should be 'short', not 'long'.
Therefore, the mistakes Gino made are as follows:
- X-rays: No error in the description.
- Infrared light: Should be 'moderate frequency' instead of 'low frequency'.
- Radio waves: Should be 'low frequency' instead of 'very low frequency'.
- Ultraviolet light: Should be 'short wavelength' instead of 'long wavelength'.
