Green light has wavelength 5×10−7m in a vacuum. the light is travelingin the +ydirection and is polarized so that the electric field is in the direction. the peak electric field has a value peak= 1 v/m.(a) write expressions for the electric and magnetic fields as a function of position andtime. make sure you indicate the direction as well as the magnitude.

Explanation:

c = Speed of light =

= Wavelength =

f = Frequency

Angular frequency is given by

Wave number is given by

Magnetic field is given by

The magnetic field amplitude is

The electric field is given by

Magnetic field is given by

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

c) up is the direction the magnetic force is acting on the charge.
