An electromagnetic wave hits a glass block and changes direction slightly as it passes through the block. Which statement correctly explains the action of the wave?

• The wave is refracted when it strikes the block, and the speed of the wave changes while passing through the block.

• The wave is refracted when it strikes the block and maintains its same speed as it passes through the block.

• The wave is reflected when it strikes the block, and the speed of the wave changes while passing through the block.

• The wave is reflected when it strikes the block and maintains its same speed as it passes through the block.
