Answer:
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
