The microwaves have a frequency of 1.8 x 10^9 Hz and travel at a speed of 3.0 x 10^8 m/s. Calculate the wavelength of the microwaves. Give your answer to two significant figures

0.17 m

Explanation:

The formula to apply in this question is that of speed of light.

The speed of the microwaves :

v = f * λ where f is frequency of the microwave, λ is the wavelength  and v is the speed of the wave

3.0 x 10⁸ = 1.8 x 10⁹ *λ

3.0 x 10⁸ / 1.8 x 10⁹ = λ

λ  = 0.16666666666

λ = 0.17 m { two significant figures}

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
