What are 2 characteristics of less divergence?

Explanation:
Less beam spread happens when the beam's aperture is larger and the wavelength is shorter. The divergence of a wave beam is roughly proportional to the wavelength divided by the aperture size (divergence ∝ λ/D). Since wavelength λ is inversely related to frequency (λ = c/f), increasing the frequency also reduces divergence. So, combining a larger diameter with a higher frequency yields the smallest, or least, divergence. This is why the best description is larger diameter and higher frequency. If you used a smaller diameter or a lower frequency, the beam would spread more.
