1)Does a photon with a high frequency has a long wavelength?
2) how do you determine an isoelectronic species from the periodic table?

1) No. According to the equation (speed of light) = (wavelength)(frequency), wavelength is INVERSELY related to frequency and therefore if a photon has high frequency it will have a small wavelength... and vice versa.
2) By writing out the electron configuration, technically. Actually isoelectronic atoms or ions just have the same electron configuration and therefore usually just the same number of electrons. For example, K+ and Cl- would be isoelectronic because they both have 18 electrons. Their electron configurations are also the same because those electrons hang out in the same spaces around the nucleus.

High frequency corresponds with high energy and short wavelength.
Things are isoelectronic when they have the same number of valence electrons. Elements in the same group or family (vertical row) are isoelectronic because they have the same number of valence electrons (except hydrogen).

he relationship is given by:
wavelength = Speed of light/ freq
where
λ = wavelength of a sound wave or electromagnetic wave
vw is the speed of propagation of the wave, and
f = frequency of the wave in 1/s = Hz.
The speed of light is a constant (3 x10^8 meters/second)
Thus think of this Wavelenght X freq is = constant so if the Freq is a big number the wavelength is a smaller number to still be constant

1) exactly opposite high frequency corresponds to small wavelengts
2) ,?
