Answer:
Black and white photography mainly depends upon the light sensitive material that helps in forming such contrasting images.
That material is AgBr.
When exposed to AgBr, the image then forms on the film.
While the image is developing, sodium sulphate, an oxidised reducing agent converts the AgBr remains into visible metallic surface.
