Visible light travels at a speed 3.0 × 108 of m/s. if red light has a wavelength of 6.5 × 10–7 m, what the frequency of this light? a) 2.2 × 10–15 hz b) 2.0 × 102 hz c) 3.0 × 108 hz d) 4.6 × 1014 hz

i think its d on edge

Answer on Edge is D.

Frequency = (3/6.5) x 10¹⁵ = 0.4615 x 10⁻¹⁵ = 4.615 x 10⁻14 second.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
