Answer:
The mnemonic I can use to memorize the metric prefixes in this order is: Gigantic Monsters Killed One Million Men Napping Peacefully. All right, so again, gigantic monsters killed one million men napping peacefully.
The light detection device is also called photodetector. It <span>transforms any natural or artificial light source it encounters into sound.
</span>Current flows in a light detection device when light collide with its pn junction.
When light falls on the junction, a reverse current flows which is proportional to the illuminance. The linear response to light makes it an element in useful photodetectors<span> for some applications. It is also used as the active element in light-activated switches.</span>
