Answer:

Velocity of the emitted electrons increases

Explanation:

Velocity is directly proportional to frequency and this can be seen from the equation

v=fλ

Hence, if the frequency increases, the velocity is bound to also increase. Thus  an increase in frequency as stated in the questions would definitely result to an increase in the velocity of the emitted electrons as seen from the equation above.

<h3>How to correct the perspective for perfect cityscape images using Photoshop?</h3>


Matching the perspective of your cityscape to reality can be difficult. You can use specialized wide-angle lenses with perspective control, known as tilt-shift lenses, but if all you have is a standard wide or ultra-wide lens, you'll have a problem. perspective distortion in your image. When you shoot large objects with a wide-angle lens, the buildings in your photo will tilt. The wider the lens, the more prone to distortion the image is.

To turn a captured scene into something that reflects reality, you need a combination of good in-camera imaging and post-processing perspective correction. In some cases, you don't want the image to reflect reality but exaggerate or emphasize distortion for emphasis. Fortunately, Photoshop has a lot of tools that allow us to adjust perspective and turn what the camera captures into the scene we see in real life.
