An electromagnetic wave in a vacuum traveling in the +x direction generated by a variable source initially has a wavelength λ of 245 μm and a maximum electric field emax in the +y direction of 6.50×10−3 v/m . if the period of the wave is then increased by a factor of 1.80, what is the equation of the resulting magnetic field component of the wave?

The resulting magnetic field component of the wave

Explanation:

Given that,

Wavelength = 245 μm

Electric field

We need to calculate the wave number and angular frequency

Using formula of wave number

The angular frequency is

If the wave period increases by a factor of 1.80 times

The maximum and related by the equation

Put the value in the equation

The magnetic field is perpendicular to the electric field.

So, the equation is

Hence,  The resulting magnetic field component of the wave

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
