Deep Dive IBDP Physics: - D.5 Electromagnetic Waves Teacher Resource Pack
Understanding the fundamental behaviors of light and nuclear radiation is key to unlocking the mysteries of both the subatomic and cosmic realms. In the IBDP Physics curriculum, students are expected to grasp not only how light and radiation behave, but also how these phenomena are measured, harnessed, and applied in modern science and technology.
To empower educators and deepen student engagement, we’re proud to present two powerful classroom resources:
Investigating Gamma Rays in Nuclear Physics
The Speed of Light and Its Constant Value
These resources provide hands-on and research-based experiences, aligning with IBDP Physics topics like electromagnetic waves, nuclear physics, and relativity. With these tools, your students can move beyond memorization to genuine conceptual mastery.
☢️ Investigating Gamma Rays in Nuclear Physics
Curriculum Link:
Topic D.5 – Electromagnetic Waves
Topic A.2 – Forces and Momentum
Topic B.4 – Thermodynamics
This rich, research-oriented resource introduces students to gamma radiation, the highest-energy electromagnetic wave, through a blend of research, simulation, and class demonstration. Students explore gamma ray production, their medical and industrial applications, and the critical safety protocols required when working with such powerful radiation.
Learning Objectives:
Understand how gamma rays are produced in nuclear decay and reactions
Analyze the biological effects of gamma radiation, including DNA mutation and therapeutic applications
Explore medical and industrial uses, including radiotherapy and equipment sterilization
Evaluate the effectiveness of radiation shielding using materials like lead and concrete
Core Activities:
Students conduct group research projects on different aspects of gamma rays (e.g., production, sterilization, cancer therapy)
Presentations incorporate visual aids, including radiation diagrams and shielding materials
Simulated demonstrations (or real if possible) explore how gamma rays pass through various substances and how different materials attenuate their intensity
Key Equations:
Attenuation formula:
where II is final intensity, μ\mu is the linear attenuation coefficient, and xx is shielding thickness
Photon energy
where EE is energy, hh is Planck’s constant, and ff is frequency
Benefits for IB Educators:
Covers nuclear physics, wave behavior, and health physics in one integrated lesson
Supports real-world application and discussion on ethical usage of radiation
Easily adaptable for IA extensions on attenuation and shielding experiments
The Speed of Light and Its Constant Value
Curriculum Link:
Topic D.5 – Electromagnetic Waves
Topic A.2 – Forces and Momentum
Topic B.3 – Thermodynamics
This interactive resource offers students a comprehensive journey through historical and modern methods of measuring the speed of light, and helps them appreciate its central role in modern physics, particularly in Einstein's theory of relativity.
Learning Objectives:
Understand the constancy of the
as a universal constantInvestigate historical experiments, from Rømer's observations to Michelson’s rotating mirrors
Conduct or simulate modern time-of-flight measurements
Explore the relationship:
between speed, frequency, and wavelength
Activity Highlights:
Students research and present on key historical breakthroughs in speed of light measurement
Perform hands-on or simulated experiments to calculate the speed of light using lasers and timing systems
