Question

without light, we would not be able to process all the things we see in our world. light allows our eyes and brains to process information about things around us. light allows us to explore colors, shadows, reflections, and many other things in the world. think about what light is made of and how it travels. which three statements are true about light? a light is made of heat and tiny particles. b light from stars can be seen from earth because light can travel through space. c light is a form of electromagnetic waves, which do not need any medium to travel. d light is not a form of energy because it cannot be measured. e light is a force as strong as gravity that can push and pull objects. f electromagnetic waves are a form of energy, therefore light is also a form of energy.

Explanation:

• Option A: Light is made of photons (particles) and is electromagnetic radiation, not heat and tiny particles. So A is false.
• Option B: Stars are in space, and light can travel through the vacuum of space, so we can see starlight from Earth. B is true.
• Option C: Light is an electromagnetic wave, and electromagnetic waves can travel through a vacuum (no medium needed). C is true.
• Option D: Light is a form of energy (e.g., radiant energy) and can be measured (e.g., intensity, wavelength). D is false.
• Option E: Light is energy, not a force like gravity. Gravity is a force, light exerts radiation pressure but isn't a force in the same way to push/pull objects strongly like gravity. E is false.
• Option F: Since light is an electromagnetic wave and electromagnetic waves are energy, light is energy. F is true.

Answer:

B. Light from stars can be seen from Earth because light can travel through space, C. Light is a form of electromagnetic waves, which do not need any medium to travel, F. Electromagnetic waves are a form of energy, therefore light is also a form of energy
