Electromagnetic and Light Waves

Front

What is the electromagnetic spectrum?

Back

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

Front

Which electromagnetic wave has the highest frequency?

Back

Ultraviolet (UV) waves have the highest frequency among the given options.

Front

Which electromagnetic wave has the longest wavelength?

Back

Radio waves have the longest wavelength among the given options.

Front

What type of waves do electromagnetic waves travel as?

Back

Electromagnetic waves travel as transverse waves.

Front

What is reflection in the context of light?

Back

Reflection is the bouncing back of light when it hits a surface, allowing us to see images in mirrors.

Front

What is diffuse reflection?

Back

Diffuse reflection occurs when light hits a rough surface and scatters in many directions, making the surface appear matte.

Front

What is the difference between specular and diffuse reflection?

Back

Specular reflection occurs on smooth surfaces, producing clear images, while diffuse reflection occurs on rough surfaces, scattering light and producing no clear image.

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 (km/s).

Front

What is the relationship between frequency and wavelength in electromagnetic waves?

Back

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

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from approximately 400 nm (violet) to 700 nm (red).
