The shortest wavelength in visible light is______.

• violet

• red

• blue

• yellow

Answer explanation

The shortest wavelength in visible light corresponds to violet, which has wavelengths around 380-450 nm. In contrast, red light has the longest wavelengths, making violet the correct answer.

Sound waves travel as ________ waves.

• Transverse

• Longitudinal

• Surface

Answer explanation

Sound waves travel as longitudinal waves, where the particle displacement is parallel to the direction of wave propagation. This is different from transverse waves, where displacement is perpendicular.

Sound is made when a source of energy forces the matter around it to __________.

• Vibrate

• Amplitude

• Stay still

• Pitch

Answer explanation

Sound is produced when energy causes surrounding matter to vibrate. This vibration creates sound waves, making 'vibrate' the correct choice, while 'amplitude', 'stay still', and 'pitch' do not accurately describe this process.

Sound waves CANNOT travel through which of these:

• Paper

• Milk

• Outer space

Answer explanation

Sound waves require a medium to travel through, such as air, liquids, or solids. Outer space is a vacuum, meaning it lacks matter, so sound waves cannot propagate there. Therefore, the correct answer is outer space.

High Amplitude =__________________

• Louder sounds

• Quieter Sounds

Answer explanation

High amplitude in sound waves indicates greater energy, which translates to louder sounds. Therefore, the correct answer is 'Louder sounds'.

What is amplitude as it refers to sound waves?

• The distance between the same two points on a wave

• The number of waves per second

• The measure of the height of the wave

• The frequency of the wave

Answer explanation

Amplitude refers to the measure of the height of the wave, indicating the strength or intensity of the sound. It is not about the distance between points or the frequency, making this the correct choice.

An ocean wave has a wavelength of 8 m and wave period of 4 s. What is the wave speed?

• 2 m/s

• 4 m/s

• 12 m/s

• 32 m/s

Answer explanation

Wave speed is calculated using the formula: speed = wavelength / period. Here, speed = 8 m / 4 s = 2 m/s. Therefore, the correct answer is 2 m/s.

The lowest part of a wave.

• frequency

• wavelength

• longitudinal wave

• amplitude

• trough

Answer explanation

The lowest part of a wave is called the trough. It represents the point where the wave reaches its minimum displacement from the rest position, contrasting with the crest, which is the highest point.
