Which limit reduces data transfer when radio wave frequency rises?

A)Increased atmospheric absorption losses
B)Reduced antenna physical dimensions
C)Increased transistor switching efficiency
D)Decreased signal modulation complexity

💡 Explanation

Increased radio wave frequency raises the atmospheric absorption losses due to electromagnetic interaction with air molecules known as dielectric losses, because higher frequencies match molecular resonance frequencies causing increased energy absorption; therefore, transfer distance decreases rather than increasing signal strength.
