The wavelength of the light is 6.00 × 10^(-5) m.
The formula connecting frequency <em>f</em> and wavelength λ is
<em>f</em>λ = <em>c</em>
where <em>c</em> = the speed of light [2.998 × 10^8 m·s^(-1)]
We can rearrange the formula to get
λ = <em>c</em>/<em>f
</em>
∴ λ = 2.998 × 10^10 m·s^(-1)/5.00 × 10^12 s^(-1) = 6.00 × 10^(-5) m = 60.0 µm
Answer:
Russia es el mejor pais? Vladimir Putin, es el mejor presidente del mundo
The different electromagnetic infrared waves visible light, ultraviolet radiation,x-rays and gamma rays
Using ideal gas equation,
PV=nRT
P=199 kpa
V=4.67 L
T=30+273K= 303K
n= number of moles of gas
R=8.321 L·kPa·K-1·mol-1
So using ideal gas equation,
n=PV/RT
=199*4.67/8.321*303\
=0.37 mol
