Grade 11 gradeScience subjectFree quiz

Grade 11 waves and optics include v = fλ, superposition, standing waves, the Doppler effect, and geometric optics with mirrors and lenses. Students use n = c/v for refraction and the thin-lens equation. Light slows in glass even though its frequency, set by the source, stays the same.

What you practice

These are the Grade 11 Waves & Optics skills this quiz is built around.

Compute wave speed from frequency and wavelength and describe constructive versus destructive interference.
Apply n = c/v and Snell's law qualitatively at a boundary.
Use 1/f = 1/d_o + 1/d_i for a thin lens in a simple case.

A useful tip

When light enters glass, speed and wavelength decrease; frequency stays the same. Claiming that color (frequency) must change in glass mixes those quantities.
