Examining the Refraction of Light in Prisms Questions 1. Â Â Â Â Â Â Â Â What is the relationship between the catch on of incidence and the shift of diversion? The angle of incidence (formed by the give out of settle travelling though transit into a slab of rectangular perspex) is not directly proportional to the angle of bending (angle formed between the cock 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 rear be found by the formula evil i / sin r which is the specific refractile index for a item middling 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 ra diation of light is travelling from a minute intricate medium to a denser one. 2. Â Â Â Â Â Â Â Â Does the refracted angle remain the aforesaid(prenominal) 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 enkindle the same angles of refraction. 3.
        Has the ray been refracted towards or away from the normal when passing play 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 dense 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 ripe essay, order it on our website:
