The wavelength of light

Determines what kind of light it is

How does infrared compare with visible light

Both are light but infrared has a larger wavelength

Both are light but infrared has a wavelength that is smaller

How does UV light compare with visible light

Both are light but UV has a wavelength that is smaller

Both are light but UV has a larger wavelength

Can be different with advantages and disadvantages

The four conditions to see an object are

Light, Clear Path, Eyes, and Object

Brain, Clear Path, Eyes, and Object

Light, Darkness, Eyes, and Object

Light, Brain, Clear Path, and Object

How is a shadow made?

When light is blocked and light illuminates the edges of the shadow

When there is absolutely no light

When white light hits a green ball

Green light is scattered and the other colors are absorbed

Green light is absorbed and the other colors are scattered

Green light is transmitted and the other colors are scattered

Green light is reflected and the other colors are scattered

When white light hits a black object

All the colors are absorbed, black is the absence of color

All the light combines to make a darker color

Some colors are absorbed and some scatter

How can we use light to turn a red object black?

By shining light that does not contain red light

By shining all the colors of light on it

By only shining red light on it

When white light hits a red filter

Red light will be transmitted and reflected, the other colors will be absorbed

Red light will be absorbed, the other colors will be scattered and reflected

Light waves with a shorter wavelength have

Higher energy and higher frequency

Higher energy and lower frequency

Lower energy and lower frequency

Lower energy and higher frequency

We cannot see most light because

Our eyes only respond to visible light which has a particular wavelength

Our eyes only respond to very long wavelengths

Our eyes only respond to very short wavelengths

From shorter to longer wavelengths, the colors of visible light go

Violet, Blue, Green, Yellow, Orange, Red

Red, Orange, Yellow, Green, Blue, Violet

Violet, Red, Green, Blue, Orange, Yellow
