Phy. Sci. Formative #2 ELM Spectrum

Front

What is the ELM spectrum?

Back

The ELM spectrum refers to the electromagnetic spectrum, which includes all types of electromagnetic radiation, ranging from radio waves to gamma rays.

Front

What are the types of electromagnetic waves in order of increasing frequency?

Back

Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, gamma rays.

Front

What is the relationship between wavelength and frequency?

Back

As the wavelength increases, the frequency decreases, and vice versa.

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light, often associated with heat.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 300,000,000 meters per second.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, due to a change in speed.

Front

What is a focal point?

Back

The focal point is the point where light rays converge after passing through a lens or reflecting off a mirror.

Front

What is the difference between opaque, translucent, and transparent materials?

Back

Opaque materials do not allow light to pass through, translucent materials allow some light to pass but not clear images, and transparent materials allow light to pass through clearly.

Front

What is the significance of gamma rays in the electromagnetic spectrum?

Back

Gamma rays have the highest energy and shortest wavelength in the electromagnetic spectrum, making them very penetrating.

Front

What color of light is bent the most when passing through a prism?

Back

Violet light is bent the most when passing through a prism.
