10 Questions
What is the formula that relates the velocity of a wave to its frequency and wavelength?
v = f λ
What type of radiation has enough energy to remove tightly bound electrons from atoms, resulting in damage to living cells?
Ionising radiation
What is the term for the bending of light as it passes from one medium to another?
Refraction
What is the term for a disturbance that travels through a medium and transfers energy from one point to another?
Wave
What is the part of the electromagnetic spectrum that is visible to the human eye?
Visible light
What is the main difference between longitudinal and transverse waves?
Longitudinal waves travel in the same direction as the wave's displacement, while transverse waves travel perpendicular to the wave's displacement
What is the primary reason why sound waves interact differently with various materials?
The speed of the sound wave is affected by the material's density and elasticity
What is the purpose of using different types of lenses and mirrors?
To focus or diverge light waves to achieve specific optical effects
How does radiation affect the human body?
Radiation can both harm and heal the human body, depending on the type and intensity
What is the primary characteristic that distinguishes wave radiation from particle radiation?
The ability to travel through a vacuum
