Answer 1

The frequency of a photon produced in a CRT with a 25.0-kV accelerating potential is approximately 9.614 x 10^15 Hz.

This correct answer is none of the above.

Step-by-step explanation:

The frequency of a photon produced in a CRT using a 25.0-kV accelerating potential can be determined using the formula:

f = eV/h

Where:

• f is the frequency of the photon
• e is the elementary charge (1.602 x 10^-19 C)
• V is the accelerating potential (25,000 V)
• h is Planck's constant (6.63 x 10^-34 J·s)

Substituting the values into the formula:

f = (1.602 x 10^-19 C) x (25,000 V) / (6.63 x 10^-34 J·s)

f ≈ 9.614 x 10^15 Hz

This correct answer is none of the above.

Your correct question is: Cineradiography framing frequencies above _ frames/sec are typically only necessary for recording pediatric coronary angiography.
