If you have an instrument that uses radiowaves with a frequency of 1.0x10^11 hz, what is the energy in joules and the wavelength in meters? use the equations c= av (i can't do the symbols) and e=hv

wavelength =  3×10⁻³ m

E = 6.63×10⁻²³ j

Explanation:

Given data:

Frequency of wave = 1.0 ×10¹¹ Hz

Wavelength of wave = ?

Energy of wave = ?

Solution:

speed of wave = wavelength × frequency

wavelength = speed of wave/ frequency

wavelength = 3×10⁸ m/s / 1.0 ×10¹¹ s⁻¹

wavelength =  3×10⁻³ m

Energy:

E = h. f

E = 6.63×10⁻³⁴ Kg.m²/s × 1.0 ×10¹¹ s⁻¹

E = 6.63×10⁻²³ Kg.m²/s²

Kg.m²/s² = j

E = 6.63×10⁻²³ j
