The flea jumps at high velocity, reaches zero velocity at the maximum height 21.1 cm before starting to fall. Solve for initial velocity given final velocity is zero.
since time is not given, use the equation:
v^2 = u^2 + 2as
convert gravity or displacement to have same units. 9.8 m/s = 980 cm/s
0 = u^2 + 2(-980)(21.1)
41356 = u^2
sqrt(41356) = u
203.4 cm/s = u

From the calculation, the wavelength of the waves is about 264 nm and belongs to the ultraviolet spectrum.
<h3>What is photoelectric effect?</h3>
The term photoelectric effect can be used to describe the loss of electron from the surface of a metal. Given that; KE = E - W, where;
KE = kinetic energy of the emitted photoelectron
E = energy of the photon
W = work function of the metal
λ= hc/E
λ=
λ= or 264 nm
