Broadcast band used by Vividh Bharati (India) Historically and in widespread practice, the Vividh Bharati programme of All India Radio has been transmitted on which broadcast band?

Introduction / Context:
Vividh Bharati is a popular entertainment and information service from All India Radio. Knowing its traditional transmission bands helps students connect receiver concepts (antenna, propagation, and selectivity) with real services in the broadcast spectrum.

Given Data / Assumptions:

• Focus on classic and widespread transmission practice.
• India’s broadcast allocations historically include MW AM for wide-area coverage.
• FM relays exist in many cities, but the core legacy is MW.

Concept / Approach:

Medium-wave AM (roughly 530–1700 kHz) has long provided extensive coverage with simple receivers. While Vividh Bharati today may also be available on FM relays and digital platforms, exam-style questions typically associate Vividh Bharati with the MW/AM band.

Step-by-Step Solution:

Verification / Alternative check:

Receiver guides and historical AIR frequency lists show numerous Vividh Bharati MW transmitters across regions.

Why Other Options Are Wrong:

Short wave has been used for international/national coverage but is not most associated with Vividh Bharati. VHF/FM is used in many cities but is not the traditional identification for exam purposes. “All of the above” overgeneralizes.

Common Pitfalls:

Assuming modern FM relays negate the traditional MW association; exam conventions usually emphasize MW for Vividh Bharati.

Final Answer:

Medium frequency (AM/MW)
