4. Calculate the wavelength (in nm) of light with a frequency of 6.05 x 104 Hz.

4.955x10¹²nm

Explanation:

It is possible to obtain wavelength from the frequency of a wave using the expression:

ν = C / λ

Where wavelength, ν, is given in m

Speed of light, C, is 2.998x10⁸m/s

And frequency, λ, is given in Hz = s⁻¹ = 6.05x10⁴s⁻¹

ν = C / λ

ν = 2.998x10⁸m/s / 6.05x10⁴s⁻¹

ν = 4955m

In nm:

4955m * (1x10⁹nm / 1m) =

4.955x10¹²nm

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
