What is wavelength in the context of waves?

Back

Wavelength is the distance between successive crests (or troughs) of a wave, typically measured in meters.

Front

What type of waves are responsible for sunburn?

Back

Ultraviolet (UV) waves are responsible for causing sunburn.

Front

What phenomenon explains why objects appear closer when viewed through water or another medium?

Back

Refraction explains why objects appear closer when viewed through a medium like water.

Front

What is refraction?

Back

Refraction is the bending of light waves as they pass from one medium to another, causing a change in speed.

Front

What part of the electromagnetic spectrum is responsible for the warmth felt from sunlight?

Back

Infrared waves are responsible for the warmth felt from sunlight.

Front

How do waves A and B differ from waves C and D in terms of wavelength?

Back

Waves A and B have the same wavelength, while waves C and D have different wavelengths.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (or about 300,000 km/s).

Front

What is the effect of temperature on infrared radiation?

Back

As the temperature of an object increases, it emits more infrared radiation.
