Wave behaviour, wave speed, and refraction take centre stage in this Grade 12 Science worksheet for Alberta Physics 30. Students connect measurable wave properties to calculations and real-world phenomena, from seismic waves recorded in Alberta to light bending through temperature layers above hot roads. The resource links equations, boundary interactions, and physical explanations so students can apply wave principles rather than simply recall definitions.

Connect wave properties to calculations

The reading passage introduces wavelength, frequency, amplitude, and wave speed, including the relationship v = fλ. Students use this equation to calculate speed or wavelength and determine frequency from the number of cycles completed over time. They also distinguish mechanical waves, such as sound and seismic waves, from electromagnetic waves such as visible light, including whether each type requires a material medium.

These concepts are applied through numerical problems using stated frequencies, wavelengths, and speeds. A seismic-wave problem asks students to calculate wavelength and show the relationship used, reinforcing both mathematical working and scientific communication.

Explore what happens at a boundary

Wave interactions become more complex when energy reaches a boundary. Students consider reflection, transmission, absorption, and refraction, with particular attention to how a change in wave speed can alter direction when a wave enters another medium at an angle. They also examine why frequency remains constant across a stationary boundary while wavelength changes when speed changes.

The examples make these ideas tangible. Alberta seismic monitoring illustrates how ground vibrations provide evidence of seismic activity and subsurface structures. Sound propagation across prairie landscapes introduces the influence of atmospheric conditions and terrain, while mirages above hot roads show how temperature differences can create air layers that bend light.

Question and activity formats

• Reading passage: introduces the key vocabulary, equation, boundary behaviour, and applied examples.

Use for guided practice or review

Use this wave physics practice resource after introducing wave terminology and the speed equation, during a lesson on boundary behaviour, or as independent review before an assessment. The combination of numerical work and real-world applications helps reveal whether students can calculate wave properties, interpret what happens at a boundary, and explain the physics behind observed phenomena. The included solutions and teacher guidance support efficient checking and follow-up discussion.
