gamma rays
ultraviolet
visible
infrared

Answer 1

the visible spectrum is roughly

400 nm (blue) — 700 nm (red)

Answer 2

so its visible?

Answer 3

you found the peak intensity to be at 200 nm

but is 200 nm: inbetween 400 nm, and 700 nm ?

Answer 4

no

Answer 5

so the radiation is shorter (is of more energy than visible)

Answer 6

which two options are possible now?

Answer 7

gamma rays?

Answer 8

that's possible, gamma rays are shorter and more intense then visible,
but there is another option too.

to be sure though, you'll have to check the numbers

Answer 9

ohh so its infrared?

Answer 10

nope, infrared are longer than visible

Answer 11

ultraviolet?

Answer 12

it turns out that gamma radiation is of wavelengths much smaller than 200 nm, <0.001 nm

Answer 13

yeah ultraviolet!

Answer 14

thanks

Answer 15

UV is roughly between 100 and 400 nm
