Opiates such as morphine sulfate stay in the system for about 72  hours. If a person has a high metabolism and is not a regular user  of the drug it could take at little as â¦48 hours for the morphine to  leave the system.
A convex mirror produces a virtual image, because the principle light rays incident on the mirror surface from the object must pass through the focal point on the other side oâ¦f the mirror (virtually), and so the image appears at a depth behind the mirror's surface.
Specular, or mirrorlike, reflection is the kind that produces visible images. Diffuse reflection is the kind that does not produce visible images. Tell the difference between specular and diffuse reflection. Relative to the wavelength of visible light, the surface of paper is like a terrain of hills and valleys. Because light is reflected from these hills and valleys in many different directions, the reflected is diffuse, or scattered.
