If a sound seems to be getting louder which of the following is probably increasing intensity frequency wavelength or speed and sound?

The sound will get louder when the amplitude of the sound pressure increases. The loudness has to do with the sound field quantity called sound pressure or sound pressure level (SPL). The sound intensity or acoustic intensity means the sound energy quantity. Our ears and the microphone diaphragms are moved by the sound pressure variations.

What is principal frequency?
Principal frequency is radiation that has the greatest intensity and the frequency increases with increasing temperature
What are the characteristic of sounds?

Does kinetic energy of photo electron depend upon intensity of light?
No. Kinetic Energy of a photon depends only on the frequency of the light (or in other words frequency of the photons which the light comprises of). Intensity of light, on the other hand, is a way to talk about how many photons are there in, say, a beam of light (putting it in simple words)!
What gamma waves have?
Gamma waves have the shortest wavelength of any electromagnetic wave in the EM spectrum, the shortest wavelength means highest cyclic frequency, and highest intensity of any EM wave. (energy transferance by gamma waves is the strongest) *intensity is a measure of the height of the sine wave as opposed to to length, essentially more energy in a smaller crossectional area.
What is two properties of sound?
Examples: frequency, intensity, wavelength.
What is principal frequency?
Principal frequency is radiation that has the greatest intensity and the frequency increases with increasing temperature
How are wavelength frequency intensity and energy in an electromagnetic wave?
You will need to have the right formula. The best one to use would be wavelength=frequency/speed of light. to find energy you would need energy=frequency*h. And intensity=power/area.
How are wavelength frequency intensity and energy related in electromagnetic wave?

What are the things that can be measured about waves?
Speed, wavelength, frequency, period, amplitude, intensity.
Does the intensity of Xrays and gamma rays differ?
Intensity is independent of frequency or wavelength. So whether it is Xray or gamma ray both can have the same intensity.
Ultraviolet rays are potentially harmful to us due to their intensity. amplitude. high frequency or long wavelength?
High Frequency.
Is red light more intense than violet light?
Intensity is independent of the wavelength/frequency.
In classical physics how does an atomic oscillator behave when heated in terms of energy emissions?
The oscillator starts at relatively low frequency and emits electromagnetic radiation of relatively low frequency (or long wavelength) and low intensity. As the heating continues, the frequency of oscillation also increases as does the frequency of the emitted radiation and the intensity of the radiation. A graph of intensity vs. wavelength would start high on the left (at short wavelengths) and fall off to the right exponentially to low intensity at long wavelengths. This graph would be at odds with the experimentally established graph of intensity vs. wavelength(which shows low intensity at short wavelengths) because the classical assumption that frequency of oscillation can increase continuously as the oscillators are heated is not correct. Frequency of oscillation can increase only in integral multiples of the fundamenal frequency.
How is the energy of a photon related to its frequency and wavelength?
wavelength : wavelength is the distance from crest of one wave to the crest of next frequency : the number of waves that passes a given point in one second energy : the amplitude or intensity of a wave energy and frequency is directly proportional to each other when energy is high frequency is also high wavelength and frequency or energy is inversly proportional to each other when wavelength is high frequency or energy is low
How do you relate characteristics of light such as colour and intensity to frequency and wavelength?
The only reasonable way to relate a frequency or wavelength (the two are related by a very simple equation, so they're effectively the same information) to a color is by looking at a table or chart; there's no mathematical equation that you can put a number in and get out "red" as the answer. Intensity has nothing to do with color, frequency, or wavelength, so there's no way to relate it to any of those properties.
Which color has the greater intensity?
A rough definition of intensity (how intense) a light is might be how bright (the brightness) the light is. Intensity speaks to the luminance or luminosity of the light source. Under that definition, either red or blue light could be more intense. But if the information regarding the energy of light according to its color (or its wavelength or frequency), we would find that a photon of blue light has more energy than a photon of red light. Blue light has a shorter wavelength or higher frequency, and electromagnetic energy with higher frequency or shorter wavelength has more energy than light of the same intensity but of lower frequency or longer wavelength.
