Examining the Refraction of Light in Prisms Questions 1. Â Â Â Â Â Â Â Â What is the relationship between the whirl of incidence and the lean of diversion? The angle of incidence (formed by the give out of settle travelling though pitch into a slab of rectangular perspex) is not directly proportional to the angle of deflexion (angle formed between the radiotherapy travelling though perspex and the normal). The interpret of the plotted angles of incidence against the angles of refraction is not a direct line and therefore demonstrates this. However, a constant shag be found by the formula evil i / sin r which is the specific refractile index for a item long suit eg. glass. Once the refractive index of a trusted medium is known, the angle of refraction can be compute if the angle of incidence and known and vice versa. The unintelligibler the medium, the large the refractive index. Usually, the angle of incidence is larger than the angle of refraction when a pecker of light is travelling from a keen intricate medium to a denser one. 2. Â Â Â Â Â Â Â Â Does the refracted angle remain the equal for incompatible angles of incidence? NO. If the angle of incidence changes, so does the angle of refraction. In no cases will differing angles of incidence set off the same angles of refraction. 3.
        Has the ray been refracted towards or away from the normal when red form air to perspex? Because the ray of light is travelling from a less dense to a denser medium (air to perspex), the ray of light will turning towards the normal, if the beam was travelling from a denser medium to a less d! ense one, it would bend away from the normal. The ray of light accounting entry the slab of perspex should be parallel to the ray of light emerging from the... If you sine qua non to get a all-inclusive essay, order it on our website:
