What is the relationship between the wavelength and the frequency of
electromagnetic radiation?

Velocity = wavelength x frequency

Wavelength = Velocity / frequency

From the above,

Wavelength is inversely proportional to frequency since the velocity of electromagnetic wave is constant.

So as the wavelength increases, the frequency decreases and vice versa

the answer is 1 i believe

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
