Question

the value of plank's constant is 6.63*10 to the power -34 Js. the velocity of light is 3.0*10 ms-1. which value is closest to the wavelength in metres of a quantum of light with frequency of 8* 10 to the power 15 s-1

Answer 1

Answer:

hope it helps you with the answer

Answer 2

Answer:

As we know that,

velocity = Frequency * wavelength

c = v * w

3 * 10 power 8 = (8 * 10 power 15) * w

w = 3* 10 power 8/ 8*10 power 15

w = 3,75,00,000 *  10 power 15

w = 3.75 * 10 power 20 m

w = 3.75 * 10 nm

approximately = 4 * 10 nm
