Question! hurry! 50 pts and

calculate the frequency of a wave with a wavelength of .0047 meters. what type of electromagnetic radiation is this?

So basically the wavelength times the frequency of an electromagnetic wave equals the speed of light.

FYI,  

λ

is the Greek letter lambda , and  

ν

is the Greek letter nu (it is not the same as a v).

Type of RadiationFrequency Range (Hz)Wavelength Range

gamma-rays1020 - 1024< 10-12 m

x-rays1017 - 10201 nm - 1 pm

ultraviolet1015 - 1017400 nm - 1 nm

visible4 - 7.5*1014750 nm - 400 nm

near-infrared1*1014 - 4*10142.5 μm - 750 nm

infrared1013 - 101425 μm - 2.5 μm

microwaves3*1011 - 10131 mm - 25 μm

radio waves< 3*1011> 1 mm

(Ultraviolet I believe, not sure)

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
