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

Where k represent the number of wave and 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:

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:

Where k represent the number of wave and 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:

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.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
