Physics

Aimed at the secondary 13-18 age group, this program enables students to undertake physics experiments which would normally require classroom blackout.

Side one offers three sub-programs: reflection at a flat surface, concave mirrors and calculations. The first part gives an explanation of angle of incidence equalling angle or reflection and then invites five entries of angles up to 45 degrees - careful, as wrong numbers produce 'nonsense in Basic' to appear and then the listing! After the graphic display, questions are asked and then a return to the menu.

We watch a concave mirror being constructed, followed by definitions of C, r and f; and then the demonstrations of beams reflected from the mirror. Questions follow, leading to further explanations, experiments, questions, etc.

Calculations teaches 1/V + 1/U + 1/F and V/U + I/S and sets examples to ensure they are understood - unfortunately another bug has appeared: 3th set?

Side two offers lens simulation, tutorial or instructions and the style is similar to that used on side one.
