Microwaves travel at the speed of light, 3.00×
108 m/s.
When the frequency of microwaves is 3.67×
109 Hz, what is their wavelength?
Answer in units of m
frequency*wavelength= wave speed
Memorize that equation. It is called the wave equation.
To find the wavelength of microwaves, we can use the formula:
Speed of light (c) = Frequency (f) x Wavelength (λ)
Rearranging the formula, we can solve for the wavelength:
Wavelength (λ) = Speed of light (c) / Frequency (f)
Given that the speed of light is 3.00×10^8 m/s and the frequency is 3.67×10^9 Hz, we can substitute these values into the equation to find the wavelength:
Wavelength (λ) = (3.00×10^8 m/s) / (3.67×10^9 Hz)
Calculating this gives us:
λ ≈ 0.082 m
Therefore, the wavelength of the microwaves is approximately 0.082 meters.
To find the wavelength of microwaves, you can use the formula:
Wavelength (λ) = Speed of Light (c) / Frequency (f)
Given that the speed of light is 3.00 × 10^8 m/s and the frequency of microwaves is 3.67 × 10^9 Hz, you can substitute these values into the formula:
λ = (3.00 × 10^8 m/s) / (3.67 × 10^9 Hz)
To simplify the calculation, you can convert the frequencies to scientific notation:
λ = (3.00 × 10^8 m/s) / (3.67 × 10^9 Hz)
= (3.00 / 3.67) × (10^8 / 10^9) m
= 0.818 m
Therefore, the wavelength of the microwaves is 0.818 m.
