A sine function can be used to model light waves. Green light has a wave length, or period of about 520 nm. Which equation best models green light?A.) y=sin 260/pi theta

B.) y= sin pi/520 theta

C.) y= sin 520/pi theta

D.) y= sin pi/260 theta

Please help

Answer 1

Answer:

Answer:

$y = A sin (kx \pm wt)$

Where k represent the number of wave $k =(2\pi)/(\lambda)$ and $w =(2\pi)/(T)$ represent the angular frequency with T the period.

For this case we know tha T = 520 nm

And the angular frequency would be given by:

$w = (2\pi)/(520)= (pi)/(260)$

So then the possible anwer for this case would be:

D.) y= sin pi/260 theta

Since is the only option with satisfy the general equation of a wave.

Step-by-step explanation:

Since the sine function can be used to model light waves we can use the following general expression:

$y = A sin (kx \pm wt)$

Where k represent the number of wave $k =(2\pi)/(\lambda)$ and $w =(2\pi)/(T)$ represent the angular frequency with T the period.

For this case we know tha T = 520 nm

And the angular frequency would be given by:

$w = (2\pi)/(520)= (pi)/(260)$

So then the possible anwer for this case would be:

D.) y= sin pi/260 theta

Since is the only option with satisfy the general equation of a wave.

What is the slope of the line that has the equation 4x+2y=12

Subtract 4x from each side:
4x-4x+2y=-4x+12 collect like terms:
2y=-4x+12 divide each term by 2
y=-2x+6 so the slope is -2 hope this helps:)

How do you write 0.01 as a percentage

It is 1%
