Compton effect
The incoming photons' energy must be in the range of an X-ray frequency to generate the Compton effect. The electron does not lose enough energy that reduces the wavelength of scattered photons towards the visible spectrum. As a result, with visible lights, the Compton effect is missing.
Recoil Velocity
The amount of backward thrust or force experienced by a person when he/she shoots a gun in the forward direction is called recoil velocity. This phenomenon always follows the law of conservation of linear momentum.
Question
![**Photoelectric Effect Calculations**
The maximum kinetic energy of electrons ejected from a metal surface exposed to 301-nm photons is 2.98 eV.
**Steps and Data to Analyze:**
1. **Find the energy of incident photons (E_γ):**
\[
E_γ = 4.11 \text{ eV}
\]
2. **Find the stopping potential (V_stop):**
\[
V_{stop} = 6.58 \times 10^{-19} \text{ V}
\]
3. **Find the work function of the metal (φ):**
\[
φ = \text{_____ eV}
\]
4. **Find the wavelength of the least energetic photon that can induce the photoelectric effect in this metal (λ_c):**
\[
λ_c = \text{______ nm}
\]
**Understanding the Parameters:**
- **Maximum Kinetic Energy (K_max)**: The energy with which electrons are ejected from the metal surface.
- **Energy of Incident Photons (E_γ)**: The energy of the photons striking the metal surface.
- **Stopping Potential (V_stop)**: Voltage required to stop the ejected electrons.
- **Work Function (φ)**: The minimum energy required to eject an electron from the metal surface.
- **Wavelength of the Least Energetic Photon (λ_c)**: The longest wavelength that can still induce the photoelectric effect.
**Note**: These values and parameters are critical in understanding the photoelectric effect and are essential in various applications, including photovoltaic cells and other light-sensitive technologies.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F08ebec3c-ee98-4c5b-879f-886a506f7e94%2F7beaa4a7-6b7c-4f89-933a-1ae82adc4f7a%2Fntbzyhs_processed.png&w=3840&q=75)
