Bab 51: 022 didn't have time to play house with her_3

The students sitting below were all very serious.

Only then did the homeroom teacher of class eight turn on the screen recording.

Sitting in the same row, Chen Zhu and Ren Wanxuan exchanged glances, the ambition in their eyes clearly visible.

Bai Lian sat attentively in her seat. Today's lecture had moved on from electromagnetism to light and dynamics, discussing polarization and single-axis crystals throughout the lesson, and even touching on Huygens' principle and dispersion.

Bai Lian noted everything. She understood quickly but didn't grasp many of the formulas.

Because she hadn't yet learned about the dispersion curve.

The lesson was difficult, and everyone listened with utmost seriousness.

At seven-thirty, when the video ended, many went up to copy it, and the homeroom teacher of class eight began to distribute today's exercises.

Bai Lian glanced at the problems. They covered an entire page and were all about optical crystals.
