Answer:
The option that best describes the relationship between frequency and wavelength of electromagnetic waves is the third option
c. The frequency increases as the wavelength decreases
Explanation:
The frequency of an electromagnetic wave, 'f', is given by the following formula;
From the above formula, the frequency of an electromagnetic wave is inversely proportional to the wavelength, and therefore, a higher frequency, ('f', to increase), requires a lower wavelength, (λ, decreases)
The correct option is that the frequency of an electromagnetic increases as the wavelength of the wave decrease.
More mass will in turn create more force in a collision.
The number of marbles in a collision will affect the outcome because they could bounce off each other and what not.
The point of origin of an epileptic seizure is called the focus. It is the part of the brain that is affected by epilepsy. This is a term used for people with partial epilepsy. The focus can be the frontal lobe, occipital lobe, mesial temporal lobe or the parietal lobe. During seizures, it is the that specific part of the brain that is being effected. Seizures happen when a surge in the electrical activities happen on certain parts. Symptoms are contractions of the muscles, blackouts and visual disturbances. Seizures can be cured and, for partial epilepsy, they are treated with AEDs or antiepileptic drugs.
The answer to the question would be Refraction.
as we know the two possible answers are refraction and reflection. The questions shows a decrease in speed thus being refraction as a ray in a reflection would not lose its speed. Hope this helps!
Answer:
1.2×10⁶ Hz
Explanation:
Applying,
v = λf............. Equation 1
Where v = speed of wave, λ = wavelength, f = frequency.
make f the subject of the equation
f = v/λ............... Equation 2
From the question,
Given: v = 3.0×10⁸ m/s, λ = 2.5×10² m
Substitute these values into equation 2
f = 3.0×10⁸/2.5×10²
f = 1.2×10⁶ Hz
