Flashcardizz: 1st Semester Exam Review #3 24 25

Front

What is the relationship between frequency and energy in waves?

Back

Higher frequency waves carry more energy.

Front

What type of signal is represented by a series of 0's and 1's?

Back

Digital Signals.

Front

What type of wave has the largest wavelength and the lowest frequency on the electromagnetic spectrum?

Back

Radio waves.

Front

What is the definition of amplitude in the context of waves?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Front

How does pitch relate to frequency in sound waves?

Back

Higher frequency sound waves produce higher pitch sounds.

Front

What is the difference between digital and analog signals?

Back

Digital signals represent data as discrete values (0's and 1's), while analog signals represent data as continuous waves.

Front

What is the formula for calculating wave speed?

Back

Wave speed = frequency × wavelength.

Front

What is the significance of wavelength in waves?

Back

Wavelength is the distance between successive crests of a wave, and it determines the wave's energy and frequency.

Front

What type of wave is used in communication technologies, such as radio and television?

Back

Electromagnetic waves.

Front

What is the effect of increasing the amplitude of a sound wave?

Back

Increasing the amplitude of a sound wave increases its loudness.
