(HT only) Explain that various substances may absorb, transmit, refract, or reflect electromagnetic waves distinctly depending directly on the applied wavelength.
(HT only) Understand that physical effects, such as refraction, intrinsically occur due to the shifting velocity of waves as they transverse through differing substances.
Construct accurate ray diagrams vividly illustrating the refraction of a wave positioned at the direct boundary between two different media.
(HT only) Use comprehensive wave front diagrams to effectively explain refraction in terms of wave speed changes occurring during medium-to-medium travel.
Describe and perform a practical investigation studying how the amount of infrared radiation absorbed or radiated by a surface is heavily influenced by the nature of that specific surface.
