What is the term for the displacement of the medium above the undisturbed position in a wave?

• Trough

• Crest

• Amplitude

• Wavelength

Answer explanation

The term 'crest' refers to the highest point of a wave, representing the displacement of the medium above its undisturbed position. In contrast, 'trough' is the lowest point, while 'amplitude' measures the height from the rest position.

What is the height of the crest to the undisturbed position called?

• Wavelength

• Trough

• Amplitude

• Elevation

Answer explanation

The height of the crest to the undisturbed position is called the amplitude. It measures the maximum displacement from the rest position, distinguishing it from other terms like wavelength or trough.

What is the displacement of the medium below the undisturbed position called?

• Crest

• Trough

• Amplitude

• Wavelength

Answer explanation

The displacement of the medium below the undisturbed position is called a trough. In wave terminology, a trough represents the lowest point of a wave, contrasting with the crest, which is the highest point.

What is the period, T, in the context of harmonic motion?

• The distance an object travels in one cycle

• The amount of time for the motion to repeat itself

• The speed of the object in motion

• The frequency of the wave

Answer explanation

In harmonic motion, the period, T, refers to the amount of time it takes for the motion to complete one full cycle and repeat itself. This distinguishes it from distance, speed, and frequency.

What does the period of a wave depend on?

• The amplitude of the wave

• The speed of the wave

• The period of oscillation of the object creating the wave

• The wavelength of the wave

Answer explanation

The period of a wave is determined by the period of oscillation of the object creating the wave. This means that the frequency and period of the source directly influence the wave's characteristics.

Where does most of the electromagnetic radiation on Earth come from?

• The moon

• The stars

• The sun

• The ocean

Answer explanation

Most of the electromagnetic radiation on Earth comes from the sun, which emits a wide range of wavelengths, including visible light, ultraviolet, and infrared radiation, making it the primary source of energy for our planet.

What characterizes electromagnetic waves?

• Speed and direction

• Color and brightness

• Wavelengths and wave frequencies

• Temperature and pressure

Answer explanation

Electromagnetic waves are characterized by their wavelengths and wave frequencies, which determine their properties such as color and energy. Thus, the correct choice is 'Wavelengths and wave frequencies'.

Which type of electromagnetic wave has the shortest wavelength?

• Gamma rays

• X rays

• UV rays

• Microwaves

Answer explanation

Gamma rays have the shortest wavelength in the electromagnetic spectrum, making them more energetic than X rays, UV rays, and microwaves. This is why gamma rays are the correct answer.
