0 votes 0 votes we can calculate wave length by using formula λ = c/ frequency , where c is velocity of light in vaccum. Please recheck with units and conversions if required Vishu Nair answered Nov 3, 2018 Vishu Nair comment Share Follow See 1 comment See all 1 1 comment reply mahabir10 commented Oct 25, 2019 reply Follow Share You are right, but the speed at which radio waves travel in vaccum is different than at which they travel in air.
