Wave Behavior at Boundaries

The video tutorial explains how waves behave when they encounter surfaces, including reflection, absorption, and transmission. It introduces key concepts like wavefronts and rays, and discusses how light interacts with opaque surfaces, following the laws of reflection and refraction. The tutorial also covers energy conservation in wave interactions and provides examples of how different materials affect light transmission.

What is the term for a line that shows the direction of a wave and is perpendicular to the wavefront?

• Frequency

• Amplitude

• Wavefront

• Ray

When waves are transmitted from one material to another, which property remains unchanged?

• Direction

• Frequency

• Wavelength

• Speed

What happens to the energy of an incident wave when it interacts with a surface?

• It is only reflected

• It is equal to the sum of the reflected, transmitted, and absorbed energy

• It is completely absorbed by the surface

• It is only transmitted

How does a black surface interact with different wavelengths of light?

• It transmits all wavelengths

• It reflects only red light

• It absorbs all wavelengths

• It reflects all wavelengths equally

What is the rule that describes the relationship between the angle of incidence and the angle of reflection?

• Angle of incidence is less than angle of reflection

• Angle of incidence is greater than angle of reflection

• Angle of incidence is equal to angle of reflection

• Angle of incidence is unrelated to angle of reflection

What is the term for the bending of light as it passes from one material to another due to a change in speed?

• Diffusion

• Refraction

• Absorption

• Reflection

In the example provided, what is the calculated wavelength of blue light in glass?

• 4.9 * 10^-9 meters

• 5.5 * 10^-9 meters

• 3.27 * 10^-9 meters

• 2.5 * 10^-9 meters
