How do the wavelength and frequency of infrared light compare to the wavelength and frequency of ultraviolet light?

According to the electromagnetic spectrum, ultraviolet light has wavelengths from 10nm to 400 nm, and infrared light from 750 nm to 1mm.

Which means that infrared light has a longer wavelength than ultraviolet light.

As for the frequency, we can use the equation that relates wavelength and frequency:

where is the wavelength , is the speed of light, and is the frequency.

What this equation tells us is that the frequency is inversely proportional to the wavelength, in other words, if the wavelength increases the frequency will decrease.

So because infrared light has a longer wavelength than ultraviolet light, infrared has a lower frequency than ultraviolet.

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

i think the answer would be b
