Question

properties of refraction

Answer 1

Refraction is the change in direction of waves that occurs when waves travel from one medium to another. Refraction is always accompanied by a wavelength and speed change. Diffraction is the bending of waves around obstacles and openings. The amount of diffraction increases with increasing wavelength.

Answer 2

'' basic properties of reflections are:
1. ( reflection 1 ) reflection maps a line to a line, a ray to ray, a segment to segment, and an angle to angle .
2. ( reflection 2 ) a reflection preserve length of an segment.
3. ( reflection 3 ) a reflection preserve mature of angle ''.........
