There is a simple relationship between the energy for a photon of light Ephoton in units of eV (electron volts) and its waveleng

Eva8 [605]

Answer:

$\lambda=620\ nm$

$E_p=1.9682\ eV$

$E_p=206.67\ eV$ is the photon energy of an x-ray

Explanation:

Given:

Energy of photon, $E_p=2\ eV$

Then according to given:

$E_p=\frac{1240}{\lambda}$

$2=\frac{1240}{\lambda}$

$\lambda=620\ nm$ is the wavelength

Again,

Energy of photon, $E_p=?$

wavelength of the light, $\lambda=630\ nm$

$E_p=\frac{1240}{630}$

$E_p=1.9682\ eV$

<u>Now, photon energy for an x-ray:</u>

wavelength, $\lambda=6\ nm$

$E_p=\frac{1240}{6}$

$E_p=206.67\ eV$ is the photon energy of an x-ray

What is the acceleration at 3 seconds?<br><br> Please explain your answer. Thank you :]

statuscvo [17]

Answer:

$-3 m/s^{2}$

Explanation:

Acceleration on a VT graph is the slope of the line at the given point. We can find the slope at 3 with Δy/Δx. This gives us (4-2)/(3-(-3)) which works out to be -3m/s^2

What affect, if any, does increasing the speed of the plunger have on the wavelength of the waves

mojhsa [17]

As the speed of the plunger increases, the wavelength of the waves decreases. The greater the frequency, the smaller the wavelength. The smaller the frequency, the greater the wavelength. When we increase the speed of the plunger, the frequency of the waves also increases, and just like with the size of the ball, it’s the speed of the plunger and the frequency of the waves are directly related.

How much time does it take for a plane To fly 5000 miles if the plane travels a speed of 500 miles per hour?

Vitek1552 [10]

Answer:

10 hours

Explanation:

If the plane flies at 500 miles per hour, it flies 500 miles every hour. So, to find out how many hours it will take to fly 5000, you simply do 5000/500.
