If your TV is AirPlay 2-enabled, then you can stream via AirPlay and AirPlay screen mirroring over the home network.
List of AirPlay 2-enabled smart TVs - Apple
Use AirPlay to stream video or mirror the screen of your Apple device - Apple Support
Supported smart TVs will have settings for AirPlay in their menus.
If your TV is not AirPlay-enabled from the factory, then you may consider an external streaming device with AirPlay capabilities, e.g. the Apple TV box.
Else you may want to consider connecting by HDMI. If your model Mac has Thunderbolt 3 or later (shaped like USB-C) but not HDMI, then you may use an additional Thunderbolt-to-HDMI adapter for that.
MacBook Air → HDMI apter → HDMI cable → TV
Note that HDMI ports, HDMI adapters, and HDMI cables have various standards that determine the bandwidth, and may restrict resolution to e.g. HD 1080p.
