In a double-slit experiment, the third-order maximum for light of wavelength 500nm is located 11mm from the central bright spot on a screen 1.6m from the slits. light of wavelength 670nm is then projected through the same slits.

how far from the central bright spot will the second-order maximum of this light be located?

The second-order maximum is located at 12 mm from the central bright.

Explanation:

The equation that describes double-slit experiment is:

(1)

with m:order of the maximum, d:distance between holes, λ:wavelength, θ: angular position of the maximum

We have to use the data given for the 500nm light to find the distance between the holes to use this value later with the 670nm light, so solving (1) for d:

(2)

Because the distance between the screen and the slit (y) is a lot bigger than the distance between the first maximum from the central bright (x), we can use the approximation:

(3)

Using (3) on (2)

Now with the value of d we can use it to calculate how far from the central bright spot will the second-order maximum is for a 670nm light using (1) and (3) solving for x:

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.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
