Amplitude, Frequency, and Wavelength

The video tutorial explains the concept of waves as energy in motion, focusing on three key aspects: wavelength, frequency, and amplitude. Wavelength is the distance between two crests or troughs, with longer wavelengths indicating lower energy. Frequency is the number of wave cycles per second, with higher frequencies corresponding to shorter wavelengths. Amplitude measures the wave's displacement from its rest position, indicating its strength or intensity. The tutorial uses ocean waves as examples to illustrate these concepts, helping viewers understand how waves behave in nature.

What is the term used for the highest point on a wave graph?

• Crest

• Frequency

• Trough

• Amplitude

How does a wave with a long wavelength compare in energy to one with a short wavelength?

• Lower energy

• Higher energy

• No energy

• Same energy

What happens to the wavelength when the frequency of a wave increases?

• Wavelength becomes zero

• Wavelength increases

• Wavelength decreases

• Wavelength remains the same

Which of the following best describes amplitude?

• The height of a wave from its rest position

• The speed of wave travel

• The distance between crests

• The number of waves per second

What effect does high amplitude have on a sound wave?

• It makes the sound quieter

• It makes the sound louder

• It has no effect on sound

• It changes the sound's pitch
