Phenomena of Lights

When a luminous ray hits a smooth polished surface and the light ray bounces off, it is called the light ___________.

• dispersion

• reflection

• refraction

• reflection

What occurs when parallel rays of light hit a rough or bumpy surface?

• Diffused reflection

• Diffraction

• Refraction

• Refular reflection

An image of a distant object caused by refraction of light is called a _______.

• Hologram

• Mirage

• Prism

• Rainbow

It is a phenomenon in which light rays get deviated from its straight path on striking an obstacle like dust or gas molecules, water vapors etc.

• Mirage

• Prism

• Rainbow

• Scaterring of Light

It is the slight bending of light as it passes about an object's edge.

• Diffraction

• Prism

• Rainbow

• Scattering of light

If the incident light ray that falls upon the surface is reflected off the object, the ray that bounces back is called ________?

• Vertical ray

• Light ray

• Reflected ray

• Incident light ray

Which explains why the fork looks different under water?

• light can't pass through the glass
• the wavelength of light lengthens
• the amount of light increases when going through water
• light is refracted at an angle

Why do we see objects as white?

• They absorb all light
• They reflect all light
• They absorb some light and reflect some light

The Law of Reflection:

The angle of the light coming in is _________ the angle of the light being reflected

• bigger than

• the same as

• smaller than

When a light wave is sucked into a surface it is called...

• Transparent

• Refraction

• Reflection

• Absorption
