Answer:
R = ρ L / A where R is the resistance and ρ the resistivity:
R2 / R1 = (L2 / A2) / (L1 / A1) = L2 * A1 / (L1 * A2)
R2 / R1 = (2 L * A) / (L * 2 A) = 1
Their resistances should be the same.
Answer:
Frequency is of light depends upon the body that emits it. While wavelength depends on the medium through which it travels in vacuum the product of wavelength and frequency is the same while in other mediums the light of higher wavelength travels faster besed on refractive index. So light velocity depends on both frequency and wavelength.
