Question

Isla made a diagram to compare X-rays and radio waves.

A venn diagram with two intersecting circles. The one on the left is labeled x-rays and the one on the right is labeled radio waves. There is an A in the one on the left, a C in the circle on the right and a B in the intersecting section.

What should Isla write in the areas marked A, B, and C?

A: Has a longer wavelength
B: Can travel only through matter
C: Has a higher frequency
A: Has a higher frequency
B: Can travel only through matter
C: Has a longer wavelength
A: Has a higher frequency
B: Travels at the same speed
C: Has a longer wavelength
A: Has a longer wavelength
B: Travels at the same speed
C: Has a higher frequency

Answer 1

To accurately categorize the properties of X-rays and radio waves in the Venn diagram, Isla should use the following attributes:

- **A (X-rays):** Has a higher frequency (X-rays have higher frequencies than radio waves)
- **B (Both X-rays and Radio Waves):** Travels at the same speed (Both travel at the speed of light in a vacuum)
- **C (Radio Waves):** Has a longer wavelength (Radio waves have longer wavelengths than X-rays)

So the best choice for Isla to write in the areas marked A, B, and C would be:

**A:** Has a higher frequency
**B:** Travels at the same speed
**C:** Has a longer wavelength
