4. calculate the wavelength of radiation with a frequency of 8.0 x 104 hz.

The wavelength of  wave is 0.375 × 10⁴ m.

Explanation:

Given data:

Wavelength of x-ray = ?

frequency of x-ray = 8×10⁴ Hz

Solution:

speed = Wavelength × frequency

Wavelength = speed /  frequency

c = 3 × 10⁸ m/s

λ= c / f

λ = 3 × 10⁸ m/s /8×10⁴ s⁻¹

λ = 0.375 × 10⁴ m

The wavelength of  wave is 0.375 × 10⁴ m.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
