What do you call a sound that you cannot hear?
Sound too low in frequency to hear (~<20Hz) is called infrasound. Sound too high infrequency to hear (~>20kHz) is called ultrasound.
What type of sound has a frequency too high to be detected by humans?
infrasonic
What frequency of a wave in the air can be heard as an audible sound by the human ear?
For the human ear, sound is audible in the range of 20 Hz (Hertz) to 20000 Hz. Sounds below 20 Hz are "infrasonic" and have too low a frequency to be heard; sounds above 20000 Hz are "ultrasonic" and are too high a frequency to be heard.
How high or low a sound is percived?
Different animals can perceive sounds at different wavelengths. For example a dog whistle has a frequency which dogs can hear but is too high for humans. Furthermore, people's sensitivity to sound frequency changes with age. In general, ordinary range for humans is 20 to 20,000 Hz.
What effects intensity?
More important for what. If you use the analogy with sound, the frequency of light is the pitch of the sound (also the frequency of the sound waves), and the intensity is how loud it is. Both are equally important, but for different reasons. Sometimes you want a low frequency, sometimes you want a high frequency. Sometimes you want low intensity, others high intensity. Depends what you want it for.

How ultrasound and infrasound differ from normal sound?
Sonic infrasound is a sound too low for humans to hear, below 20 Hertz. Ultrasound is a sound too high for humans to hear, above 20,000 Hertz.

What name is given to the sounds which a cat can hear but a human cannot?
Sound with a frequency lower than about 20 cycles per second, called infrasonic sound. Sound with a frequency higher than about 20,000 cycles per second, called ultrasonic sound. Only those with excellent hearing can perceive sound at these extremes. As we age and as our hearing is damaged by exposure to loud sounds, the frequency range of hearing is reduced. Some animals can hear sounds above and below the range of humans.
If the frequency of an electromagnetic wave is too high or too low?

Why dog whistle is heard by dog but not man?
The frequency of the sound is too high for humans to hear, but dogs have more sensitve ears and can hear at higher frequencies.
What is the fate of the energy in the ultraviolet light incident on glass?
Ultraviolet is too high frequency to enter glass and infrared is too low.
