Waves are ... -Specular- Wave ... in a single direction by a smooth surface. Diffuse- Waves are ... by a rough surface so ... rays go off in multiple directions (9) 10. ... is the number of complete waves passing a certain point per second. Measured in hertz (9) Down 1. ... is speed of energy being transferred (4, 5) 2. ... can be absorbed, reflected or transmitted. Absorbed- By the material the wave is trying to cross, transfers energy to material energy stores . Transmitted- Waves carry on travelling through, leads to refraction often. (5) 5. ... -Imaginary line that is perpendicular to the surface at point of incidence. Usually shown as a dotted line (6) 6. ... of incidence= ... of reflection (5) 7. ... waves- the oscillations are perpendicular to the direction of energy transfer. All electromagnetic waves, Ripples and waves in water, wave on a string (10) 8. All ... are either transverse or longitudinal (5)
