As you move left to right on the electromagnetic spectrum, the frequency of the waves?AincreasesBdecreases

To answer the question about the behavior of frequency as one moves left to right on the electromagnetic spectrum, let’s analyze the concept of the electromagnetic spectrum and the relationships between frequency, wavelength, and energy.

Analysis

1. Understanding the Electromagnetic Spectrum: The electromagnetic spectrum encompasses all types of electromagnetic radiation, ranging from radio waves with long wavelengths to gamma rays with very short wavelengths.

2. Relationship Between Frequency and Wavelength: Frequency ($f$) is inversely related to wavelength ($\lambda$) as expressed by the formula: $c = f \cdot \lambda$ Where $c$ is the speed of light in a vacuum (approximately $3.00 \times 10^8 \, \text{m/s}$). As one moves from left to right across the spectrum (from radio waves to gamma rays), the wavelength decreases.

3. Effect on Frequency: Since frequency is inversely proportional to wavelength, as the wavelength decreases, the frequency must increase. This means that moving from left to right on the electromagnetic spectrum results in higher frequencies.

Conclusion

The question asks for the behavior of frequency as you move left to right on the electromagnetic spectrum. Therefore, the correct choice is:

A. Increases

Final Answer

The frequency of the waves increases as you move left to right on the electromagnetic spectrum.
