Wave Behaviors

What is the principle of absorption in wave behavior?

• Absorption is when a wave is reflected back into the medium.

• Absorption is when a wave is taken in by a material and converted to other forms of energy, such as heat.

• Absorption is when a wave travels through a material without any change.

• Absorption is when a wave splits into multiple waves of different frequencies.

What is the definition of amplitude in wave behavior?

• Amplitude is the maximum distance that the wave moves away from its rest position.

• Amplitude is the frequency of the wave measured in hertz.

• Amplitude is the speed at which the wave travels through a medium.

• Amplitude is the wavelength of the wave measured in meters.

What is the difference between a concave lens and a convex lens?

• A concave lens converges light rays, while a convex lens diverges light rays.

• Both concave and convex lenses diverge light rays.

• A concave lens diverges light rays, while a convex lens converges light rays.

• A concave lens and a convex lens have the same effect on light rays.

What is the difference between transparent and opaque objects?

• Transparent objects allow all light to pass through, while opaque objects do not allow any light to pass through.

• Opaque objects allow some light to pass through, while transparent objects do not allow any light to pass through.

• Both transparent and opaque objects allow all light to pass through.

• Transparent objects reflect all light, while opaque objects absorb all light.

What happens to light waves when they pass through a prism?

• They reflect and bounce back.

• They refract and separate into different colors, creating a spectrum.

• They absorb all colors and appear white.

• They travel straight without any change.

What type of wave requires a medium to travel through, such as air or water?

• Mechanical wave

• Electromagnetic wave

• Surface wave

• Transverse wave

What happens to the speed of sound when it moves from air into water?

• The speed of sound decreases because sound travels slower in water than in air.

• The speed of sound remains the same when moving from air to water.

• The speed of sound increases because sound travels faster in water than in air.

• The speed of sound becomes unpredictable when transitioning from air to water.

What is the definition of frequency in relation to waves?

• Frequency is the number of waves that pass a point in a given period of time, usually measured in Hertz (Hz).

• Frequency is the speed at which waves travel through a medium.

• Frequency is the amplitude of the waves measured in decibels (dB).

• Frequency is the distance between two consecutive peaks of a wave.

What is the definition of reflection in wave behavior?

• The bending of a wave as it passes through a medium.

• The bouncing back of a wave when it hits a surface that it cannot pass through.

• The absorption of a wave by a material it encounters.

• The scattering of a wave in different directions after hitting a surface.

What type of object allows only some light to be transmitted and looks blurry?

• Opaque object

• Transparent object

• Translucent object

• Reflective object
