Question

CAN SOMEONE HELP ME
Blue light has a wavelength of about 4.5 x 10-7 m. Find the energy of this wave.

Answer 1

can someone nice plzz help me

Answer 2

Do you know anything about wavelengths/waves so far ?

Answer 3

no this topic is new to me

Answer 4

10-7 or 10 to the power of -7

Answer 5

Blue light is a type of EM radiation, and it turns out that all types of EM radiation have the same velocity, c (the speed of light ~3E8 m/s). Now since the frequency of a wave is the ratio of the velocity of the wave to the wavelength: frequency = velocity/wavelength And f = (3*10^8 m/s)/(4.7*10^-7 m/s)= 6.4E14 Hz

Have a nice day.
