Hoyt’ s Demonstration _ Demonstrations showing that water, sound and light acted in waves were the focus of Miss Ros- alie C. Hoyt’s lecture on Ripples, Waves, and Light. Using ‘some equipment including a T.V. set borrowed for the occa- sion, she explained the general principle of interference of waves or ripples (little waves) and kept her promise “not to write any mathematical formulae on_ the blackboard.” Ripples started by a paddle in a dish of water appeared as straight lines on the TV screen. When the ripples hit a brass plate with one notch, the patterh™became a series of -arcs like the ripples after—a stone has been thrown into water. A plate with two notches gave a pattern which looked like inter- rupted length-wise halves of figure eights. Each notch was causing a series of arcs and the interruptions were flat--places -which~ resulted when a wave from one notch met a trough from another. This is call- ed interference. In other places, two waves form. ed an extra-high wave and two troughs formed a doubly deep trough. This is called reinforce- ment. Because sound and light also exhibit reinforcement and in- terference they are thought to move in waves. A high-pitched sound was beam- ed toward a plate with two rec- ESPADRILLES Criss-Cross Straw-Soled Bath Slippers $1.50 at the MEXICAN SHOP Bryn Mawr, Pa. tangular holes in it. An “applause” meter registered several changes from maximum to minimum vol- ume as the microphone was moved in an are toward one end of the plate. The minima were at places where the waves from each hole interfered with each other. When the holes were closer together or when the pitch was lower there were fewer fluctuations . During a sound wave the air is alternately stretched and compressed.

Contrary to traditional opinion, Mr. Sprague feels that the taste of these audi- ences should not be blamed for the things we do not like in Shakes- peare.

The action in these plays moved so smoothly and rapidly that the ob- server forgot about the obvious lack of scenery. The absence of scenery gave the poet the chance to create atmosphere through the lines themselves. The Elizabethan stage was far from crude.
