Q: In the photoelectric effect, what is the effect of increasing the frequency of incident light beyond the threshold frequency?

Solution: Increasing the frequency beyond the threshold increases the kinetic energy of the emitted electrons, as per the equation KE = hf - φ.

Steps: 6

Step 1: Understand the photoelectric effect. This is when light hits a material and causes it to emit electrons.
Step 2: Know what the threshold frequency is. This is the minimum frequency of light needed to release electrons from the material.
Step 3: Realize that if the frequency of the light is increased beyond this threshold frequency, electrons will still be emitted.
Step 4: Learn about the equation KE = hf - φ. Here, KE is the kinetic energy of the emitted electrons, h is Planck's constant, f is the frequency of the light, and φ (phi) is the work function (the energy needed to release an electron).
Step 5: Notice that as you increase the frequency (f) of the light, the kinetic energy (KE) of the emitted electrons also increases because you are subtracting a constant (φ) from a larger number (hf).
Step 6: Conclude that increasing the frequency of the incident light beyond the threshold frequency results in higher kinetic energy for the emitted electrons.
