What is the wavelength of a wave with frequency 1.4 x 1010Hz?

2.143 × 10^-2m

Explanation:

The wavelength, denoted by λ, can be determined using the formula;

λ = v/f

Where; λ = wavelength (m)

v = speed of light (3 × 10^8m/s)

f = frequency

According to the provided information, f = 1.4 x 10^10Hz, v = 3 × 10^8m/s

Hence, λ = v/f

λ = 3 × 10^8/ 1.4 x 10^10

λ = 2.1428 × 10^(8-10)

λ = 2.143 × 10^-2m

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
