how do you find the intensity of a wave?

• Intensity is the same as frequency.
• Intensity can be found using the formula F = ma.
• Intensity of a wave is calculated I = A^2

• Intensity is measured in decibels.

what is the name for the height of a wave?

• Amplitude
• Crest
• Wavelength
• Frequency

how many electrons are in the hydrogen atom?

• 0
• 2
• 3
• 1

• What is the rydberg equation

• 1/λ = R (1/n1² - 1/n2²)

• 1/λ = R (1/n1² + 1/n2²)

• λ = R(n1² - n2²)

• 1/λ = R(1/n1 + 1/n2)

frequency is defined as what and is found in what units

• Frequency is the number of occurrences of an event per unit time, measured in Hertz (Hz).
• Frequency is the distance between two waves, measured in meters.
• Frequency is the speed of sound in air, measured in meters per second.
• Frequency is the total amount of energy in a system, measured in Joules.

given the speed of light and the frequency, how would you find the wavelength of a wave?

• wavelength = frequency / speed of light
• wavelength = speed of light / frequency
• wavelength = speed of light + frequency
• wavelength = speed of light - frequency

whats the difference between the balmer series and lyman series?

• The Balmer series is for infrared light, while the Lyman series is for radio waves.
• The Balmer series emits visible light, while the Lyman series emits ultraviolet light.
• The Balmer series emits X-rays, while the Lyman series emits gamma rays.
• The Balmer series is a hydrogen emission spectrum, while the Lyman series is for helium.
