Environmental Hazards are usually any chemicals that donot naturally occur to exist anywhere and are usually made in the fields of industry or experimental sciences
So if you happen for example to throw a bit of mercury in some river while being in a school trip then this is an environmental hazard created by humans
The answer is True . The precision of a measuring is based on the fitness of its scale subdivisions
I believe the answer is C, AgBr. I hope this helps
Good afternoon,
Infrared light wavelengths = 1,000 nm - 750 nm
Visible light wavelengths = 750 nm - 400 nm
UV (Ultraviolet) light wavelengths = 400 nm - 10nm
So, the correct order is Infrared - Visible - Ultraviolet
I hope this has satisfied you, and if you need anymore help, feel free to ask.
Have a good afternoon!
