... into two parts. A filter can eliminate one of these – but the other one will only be dimmed. This is because lasers are already polarized and one beam has most of the intense laser light, which a single filter cannot block completely. At this point you could have small groups discuss how to act out ...

... depend on frequency. It can be explained by the fact that when oscillations of U1 and U2 occur in anti-phase then the instantaneous voltage distribution in the lens is antisymmetric, and the voltage in the aperture center is always zero. However, because the rms voltage in central region falls below ...
