Electromagnetic Spectrum Quiz

Relationship Between Frequency and Wavelength

• Frequency and wavelength are inversely related; as one increases, the other decreases.
• The formula relating them is ( c = \lambda \times f ), where ( c ) is the speed of light, ( \lambda ) is the wavelength, and ( f ) is the frequency.
• High frequency corresponds to short wavelength; low frequency corresponds to long wavelength.

Relationship Between Energy and Wavelength

• Energy and wavelength are also inversely related; shorter wavelengths have higher energy.
• The relationship can be expressed as ( E = \frac{hc}{\lambda} ), where ( E ) is energy, ( h ) is Planck's constant, and ( c ) is the speed of light.
• Higher energy photons (like gamma rays) have shorter wavelengths, while lower energy photons (like radio waves) have longer wavelengths.

Relationship Between Frequency and Energy

• Frequency and energy share a direct relationship; higher frequency results in higher energy.
• The relationship is defined by ( E = hf ), where ( f ) is frequency and ( h ) is Planck's constant.
• Electromagnetic waves with high frequency, such as x-rays, are more energetic compared to those with low frequency, like microwaves.

Comparison of Frequency

• Gamma rays possess the highest frequency in the electromagnetic spectrum.
• Radio waves exhibit the lowest frequency, making them the opposite end of the spectrum.

Comparison of Energy Levels

• Radio waves have the lowest energy among electromagnetic waves due to their long wavelengths.
• Gamma rays have the highest energy due to their short wavelengths and high frequencies.
