THIRD PERIODICAL TEST IN SCIENCE 7


S.Y. 2024-2025

I. Directions: Write TRUE if the statement is correct and FALSE otherwise. Write the correct
answer on the space provided before each number.

________1. More disturbances in the medium generate more waves, and stronger disturbances
create smaller waves.
________2. A flag swaying in the wind is an example of mechanical wave.
________3. Solids are the best medium for waves to travel.
________4. Just like any wave, electromagnetic waves require a medium to transfer energy from one
location to another.
________5. Of all the electromagnetic waves, gamma rays have the lowest frequency and thus have
the lowest energy.
________6. A surface wave is a type of wave in which the particles of the medium move in a circular
motion.
________7.The loudness of a sound cannot be measured.
________8. Sound can be transmitted in a vacuum because there are particles that will vibrate and
transmit sound.
________9. Humans can hear sounds below 20 Hz.
________10. The distance from the trough to the crest of a wave is equal to the amplitude of the
wave.
II. Directions: Identify the following.
_______________1. It is the number of waves that pass a point along a medium.
_______________2. It is a succession of points where particles move close to one another.
_______________3. It is the topmost portion of a wave.
_______________4. It is formed in a series of disturbances.
_______________5. It is the length of time during which a single wave is produced.
_______________6. It is defined as the capacity of an object or a system to do work and carry out
vigorous activity.
_______________7. These are sounds that have frequencies of more than 20,000 Hz.
_______________8. It is the smallest bone found in the ear.
_______________9. It refers to the highness or lowness of a sound.
_______________10.It is the material through which waves are transmitted.
III. Directions: Identify what type of wave the following waves are. Choose only the letter of the
correct answer.
A. Transverse B. Longitudinal C. Surface Waves
_____1. sound waves _____6. vibrations on a guitar string
_____2. ocean waves _____7. radio waves
_____3. seismic waves _____8. tsunami waves
_____4. light waves _____9. waving flag
_____5. ultrasound waves _____10. gravity waves
IV. Solve for the following. Write your answer on the space provided. Use a separate sheet of
paper for your solution. NO SOLUTION WILL BE MARKED WRONG.

_______________1. A wave travels at a velocity of 3.0 x 10 8 m/s. If its frequency is 5.0 x 1014 Hz,
what is its wavelength?
_______________2. A sound wave has a wavelength of 2 meters. If the wave’s speed in air is
340m/s, what is its frequency?
_______________3. If light has a wavelength of 500mm, what is the frequency of this light?
_______________4. A wave has a frequency of 60Hz and a wavelength of 500cm. What is the
velocity of the wave?

travels at the speed of light?
