Question

According to Einstein’s model, the threshold frequency for a metal having work function ϕ₀ is given by _________.

Options

• ϕ₀h

• ϕ₀h + 100

• `phi_0/"h"`

• `"h"/phi_0`

Answer 1

According to Einstein’s model, the threshold frequency for a metal having work function ϕ0 is given by `underline(phi_0/"h")`.

Explanation:

The minimum frequency of incident light that can generate photoelectric emission is known as the threshold frequency.

Work Function, `phi_0 = "h"nu_0`

Thus, `nu_0 = phi_0/"h"`
