Consider a room heater that uses a concave mirror to reflect infrared radiation from hot coils. The mirror has a radius of curvature of 49.0 cm and produces an image of the coils 3.30 mmirror. Calculate the intensity of IR radiation in W/m² projected by the concave mirror on a person 3.30 m away. Assume that the heating element radiates 1,450 W and has an area ofthat half of the radiated power is reflected and focused by the mirror.W/m²

Given:- Radius of curvature of the mirror, R=−49.0cm (negative because the mirror is concave)-…
