If you are preparing for the HSC Physics Question Bank with Important Questions – Communication Systems 2026, you have come to the right place. As the 2026 board examinations approach, students across Maharashtra are looking for a clear roadmap to tackle Chapter 16 of the Physics syllabus. This chapter is not just a theoretical unit; it is the backbone of our digital world, from mobile networks to high-tech medical telemetry.
The HSC Physics Question Bank with Important Questions – Communication Systems 2026 is designed to help you understand the core elements of how information travels. Whether it's the basics of a transmitter or the complexities of bandwidth in 5G and 6G networks, this guide covers everything you need to score full marks in this section.
HSC Physics Question Bank with Important Questions – Communication Systems 2026: Chapter Overview
The Communication Systems chapter in the HSC Physics syllabus usually carries a weightage of 2 to 3 marks (extending up to 5 marks with options). While it may seem like a small chapter, its questions are direct, diagram-based, and highly scoring. For the 2026 session, the Maharashtra State Board (MSBSHSE) has emphasized application-based learning, particularly how communication principles apply to modern medical diagnostics and remote surgery.
Why This Chapter is Important for 2026
With the global shift towards 6G research and the integration of AI in telecommunications, the 2026 exam paper is expected to feature questions that connect textbook theory with real-world advancements. Understanding the "Elements of a Communication System" is no longer just about passing an exam; it's about understanding the technology that powers your smartphone and the latest medical "Internet of Things" (IoMT) devices.
Core Elements of Communication Systems
Every communication setup, regardless of its complexity, follows a fundamental structure. This is a favorite area for the HSC Physics Question Bank with Important Questions – Communication Systems 2026.
Information Source: The origin of the message (voice, data, or image).
Transmitter: Processes the message into a signal suitable for transmission.
Channel: The medium (wire, fiber optic, or air) through which the signal travels.
Receiver: Extracts the original message from the received signal.
User of Information: The final destination.
Important Formulas for Communication Systems
While you don't need to memorize long derivations for this chapter, you must be familiar with the following formula names to solve numerical problems:
Modulation Index Formula (Ratio of amplitudes)
Bandwidth of Amplitude Modulation (AM)
Range of Transmission Antenna (Relation between height and distance)
Maximum Line-of-Sight Distance (Between transmitting and receiving antennas)
Critical Frequency of Ionosphere
Top Important Questions for 2026 Board Trends
After analyzing the last five years of MSBSHSE papers and the official SCERT question banks, we have identified the most repeated and high-probability questions.
Very Short Answer Questions (1 Mark)
Define the term 'Modulation'.
What is 'Attenuation' in a communication system?
Name the three basic modes of propagation of electromagnetic waves.
What is the function of a 'Transducer'?
Short Answer Questions (2 Marks)
Distinguish between Ground Wave and Sky Wave propagation.
Why is modulation necessary for long-distance communication? (List at least two reasons).
Explain the concept of 'Bandwidth' in brief.
Medical Focus: Briefly explain how communication systems are used in remote patient monitoring.
Short Answer II / Long Answer (3–4 Marks)
Draw a neat, labeled block diagram of a basic communication system and explain each part.
Describe the process of Amplitude Modulation (AM) with the help of waveforms.
Explain Space Wave propagation and derive the formula name for the range of a transmission antenna.
What is the "Need for Modulation"? Discuss antenna size and power considerations.
2026 Trends: Medical Applications and Future Tech
In 2026, the intersection of Physics and Medicine is a major highlight. High-speed communication is the reason "Telesurgery" is becoming a reality.
Latency in Healthcare: For a surgeon in Mumbai to operate on a patient in a rural clinic, the communication system must have "Ultra-Low Latency."
Sensors and IoMT: Body-worn sensors use wireless communication to send heart rates and glucose levels directly to a doctor’s cloud.
6G Vision: By 2026, we are looking at 6G roadmaps that promise "Haptic Communication," where doctors can actually "feel" the texture of tissues through a robotic interface.
How to Use the Official Maharashtra Board Question Bank
