**25 POINTS**. I doubt anyone will do this but it's worth a try to ask. To do this exercise, you will need fifteen containers, f

ive large, five medium, and five small. The "large" containers should be about the size of a soda pop can. The containers do not have to be transparent but they need to be shaped so that you will be able to easily pour water from them into a graduated cylinder. You will also need at least one 100-mL graduated cylinder. Ideally, you will also have a larger and smaller cylinder to use. (If, perhaps, you are using kitchen measuring cups instead of graduated cylinders, they need to have metric markings on them. Be sure to use the metric markings!) Be sure to read the volumes at eye level and at the bottom of the meniscus.
Make a supply of colored water to use in this experiment. Colored water will make it easier to read the meniscus.
Before you start, make a chart in which to record your estimates and actual values. You will also need your phone to take a picture of the large, medium, and small containers you are using to estimate the volume of water, as well as a picture of the graduated container you are using for the actual measurement.
Fill one of the large unmarked containers with colored water, estimate the volume in milliliters (mL) and put it into your chart.
Then carefully pour it into the graduated container to measure the actual water volume. Put the measurement into your chart.
Repeat this procedure with the other four "large" containers. When you have completed this task with the large containers, move on to the medium and small containers.
For the large containers, record your estimated volumes first, then determine the actual volumes and record these figures. Include the pictures that you took. For the medium containers, record your estimated volumes first, then determine the actual volumes and record these figures. Include the pictures that you took.
For the small containers, record your estimated volumes first, then determine the actual volumes and record these figures. Include the pictures that you took.

Calculate the linear momentum of photons of wavelength<br> (a) 600 nm,<br> (b) 70 pm,<br> (c) 200 m.
lubasha [3.4K]

Answer:

a) p = 1.10 * 10⁻²⁷ kg·m/s

b) p = 9.46 * 10⁻²⁴ kg·m/s

c) p = 3.31 * 10⁻³⁶ kg·m/s

Explanation:

To solve this problem we use the <em>de Broglie's equation, </em>which describes the wavelenght of a photon with its momentum:

λ=h/p

Where λ is the wavelength, h is Planck's constant (6.626 * 10⁻³⁴ J·s), and p is the linear momentum of the photon.

Rearrange the equation in order to solve for p:

p=h/λ

And now we proceed to calculate, <u>keeping in mind the SI units</u>:

a) 600 nm= 600 * 10⁻⁹ m

p=(6.626 * 10⁻³⁴ J·s) / (600*10⁻⁹m) = 1.10 * 10⁻²⁷ kg·m/s

b) 70 pm= 70 * 10⁻¹² m

p=(6.626 * 10⁻³⁴ J·s) / (70*10⁻¹²m) = 9.46 * 10⁻²⁴ kg·m/s

c) 200 m

p=(6.626 * 10⁻³⁴ J·s) / (200m) = 3.31 * 10⁻³⁶ kg·m/s
