Web27. okt 2024. · Find 1 Answer & Solution for the question The principal section of a glass prism is an isosceles triangle ABC with AB = AC. One face AC of the glass prism is silvered. If a ray is incident normally on the face AB and after two reflections, it emerges from the base BC perpendicular to it, what is the measure of angle BAC? Please help me … WebHighly silvered mirrors reflect about 9 8 % of the incident light. With a 2-mirror periscope, that results in approximately a 4 % decrease in intensity of light as the light passes through the periscope. This may not seem like much, but in low-light conditions, that lost light may mean the difference between being able to distinguish an enemy armada or an iceberg …
WebThe cross-section of a glass prism has the form of an isosceles triangle. One of the refracting faces is silvered. A ray of light falls normally on the other refracting face. After being reflected twice, it emerges through the base of the prism perpendicular it.
