How do we detect sound in our ears? Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.
What skin conditions does a Wood’s lamp reveal? A Wood’s lamp can be used to detect bacterial or fungal skin infections.

Can a black light show skin cancer?

Are heat detectors the same as smoke detectors?
In a nutshell, here’s the difference between heat detectors and smoke detectors: Heat detectors are intended to minimize property damage by reacting to the change in temperature caused by a fire. Smoke detectors are intended to protect people and property by generating an alarm earlier in the development of a fire.
