Question 21

What is sound?

Answer 21

Sound is a vibration that travels through a medium (solid, liquid, or gas) and can be heard when it reaches the ear.

Answer 25

When light bounces off a surface.

Question 26

Question 29

What are the main parts of the ear and their functions?

Answer 29

Outer Ear • Parts: • Pinna (Auricle): The visible part that collects sound waves. • Ear Canal: A tube that channels sound toward the eardrum. • Function: Captures sound waves and directs them into the ear canal toward the eardrum. 2. Middle Ear • Parts: • Eardrum (Tympanic Membrane): Vibrates when sound waves hit it. • Ossicles: Three tiny bones—malleus (hammer), incus (anvil), and stapes (stirrup)—that amplify and transmit vibrations. • Eustachian Tube: Balances pressure between the middle ear and the outside environment. • Function: Converts sound waves into mechanical vibrations and amplifies them for the inner ear. 3. Inner Ear • Parts: • Cochlea: A spiral-shaped organ filled with fluid and lined with hair cells that convert vibrations into nerve signals. • Semicircular Canals and Vestibule: Control balance and spatial orientation. • Auditory Nerve: Carries signals from the cochlea to the brain. • Function: Translates mechanical vibrations into electrical signals (for hearing) and helps maintain balance.

In straight lines

Question 31

How do you work out time?

Answer 31

Distance divide by Speed

Question 32

How do you work out speed?

Answer 32

Question 33

What happens when light hits a translucent object?

Answer 33

Some light passes through, but it’s scattered (e.g., frosted glass).

Question 34

What is refraction?

Answer 34

Refraction is the bending of light as it passes from one material to another (like air to water).

Question 35

What are the 7 colors of the visible spectrum?
