An electromagnetic wave of wavelength 435 nm is traveling in vacuum in the –z direction. the electric field has an amplitude of 2.70×10−3v/m and is parallel to the x axis. what are the frequency and the magnetic-field amplitude of this wave?
Answers: 1
. Since its wavelength is 
, we can find the frequency of the wave by using the relationship between f, 
and c:

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
